Returns hotels with side-by-side cash vs points rates, cents-per-point (CPP) valuation,
and deal scores so you can recommend the best value. This is Gondola's unique advantage —
no other travel search shows both cash and points rates together.

Args:
    location: City name, address, or area to search (e.g. "Tokyo", "Manhattan, New York", "near LAX airport").
    checkin: Check-in date in YYYY-MM-DD format (e.g. "2026-04-15").
    checkout: Check-out date in YYYY-MM-DD format (e.g. "2026-04-20").
    num_adults: Number of adult guests. Defaults to 2.
    chain_name: Optional hotel chain to filter by (e.g. "marriott", "hilton", "hyatt", "ihg").
        Case-insensitive substring match against each result's chain. If nothing matches, the
        unfiltered results are returned with an explicit note so you don't keep retrying.
    loyalty_programs: Optional list of the user's loyalty programs (e.g. ["hilton_honors", "marriott_bonvoy"]).
        When provided, results include personalized earnings and tier benefits like 5th night free.
    loyalty_points: Optional dict of program name to points balance (e.g. {"hilton_honors": 250000}).
        When provided, results indicate whether the user can afford each hotel with points.
    limit: Max number of hotels to return (default 20). The response notes how many more exist
        and how to narrow; raise this only when the user explicitly wants a longer list.

Returns:
    Formatted list of hotels with cash rates, points rates, CPP valuation, and deal recommendations.

Use this after search_hotels to get full details for a hotel the user is interested in.
Returns room options with pricing, cancellation policies, and amenities.

Args:
    hotel_id: The hotel's Vervotech property ID (returned by search_hotels).
    checkin: Check-in date in YYYY-MM-DD format.

    checkin: Check-in date in YYYY-MM-DD format.
    checkout: Check-out date in YYYY-MM-DD format.

Returns:
    Side-by-side comparison of cash vs points rates with recommendations.

Returns a link to Gondola's checkout for this hotel, where the traveler reviews the room
and completes payment on the web. This is the booking path for this connection.

(Connections belonging to an approved booking partner — which requires the mcp:book OAuth
scope — additionally get an in-conversation option here. If you don't see booking tools in
your tool list, this connection isn't one of those, and the link is the way to book.)

Use this after search_hotels or get_hotel_details when a user wants to book.
Pass ``gondola_rate_id`` whenever a specific rate has been surfaced (from
get_hotel_details or compare_rates) so the link lands on that rate's
checkout page instead of the generic hotel page.

Args:
    hotel_id: The hotel's Vervotech property ID (from search_hotels results).
    checkin: Check-in date in YYYY-MM-DD format.
    checkout: Check-out date in YYYY-MM-DD format.

        the link deep-links straight to that rate's checkout page.

frequent routes, past airlines, raw seat-assignment evidence, and favorite-seat or
aisle/window/side/row preference questions.

Requires a Gondola account (API key).

Args:
    limit: Max number of past trips to return, most recent first (default 20). The response
        notes how many more exist; raise this only when the user wants their full history.

estimated cash value, recent points changes, and expiration dates.

Args:

    checkout: Check-out date in YYYY-MM-DD format.
    num_adults: Number of adult guests (default: 2).

Returns:
    List of similar hotels with rates and ratings.

Trip-independent. Looks across every loyalty program the user holds — plus the transferable
card currencies (Amex, Chase, Bilt, etc.) that can feed hotel programs — and reports points
expiring soon (ranked by value at risk), the best transfer opportunities, and the largest
balances. When the user's travel profile is available, it also tailors the view to their home
airport, the airlines they fly, their frequent destinations, and when they travel (e.g.
flagging points that expire before their usual travel months). Takes no arguments.

Use this when the user asks how to make the most of their points, what's expiring, or where
they can transfer. For deciding where to book a specific trip, use search_hotels /
compare_rates instead.

Returns:
    A Markdown portfolio summary, or instructions to connect accounts when none are linked.

Results are ranked for the traveler by the search backend — weighing their airline
loyalty/status and travel history alongside flight quality — and returned 10 per page.
To see more options, call again with ``page=2``, ``page=3``, and so on.

Args:
    origin: Origin airport code or city (e.g. "LAX", "SFO", "New York").
    destination: Destination airport code or city (e.g. "NRT", "LHR", "Paris").
    departure_date: Departure date in YYYY-MM-DD format (e.g. "2025-03-15").
    return_date: Optional return date in YYYY-MM-DD format for a round trip. In browse
        mode, round trips are searched as two one-way legs.
    num_passengers: Number of passengers. Defaults to 1.
    cabin_class: Optional cabin class preference. One of:
        "economy", "premium economy", "business", "first".
    mode: Leave as "browse" (default). "book" is a restricted alpha — only use it if
        the user explicitly asks to book a flight.
    page: 1-based results page, 10 options per page. Increment to see more options.
    airlines: Optional airline codes or names for browse mode (e.g. ["UA"] or
        ["United"]). Passed to the Google Flights search API.
    max_stops: Optional maximum stops per direction in browse mode. Use 0 for
        nonstop only, 1 for nonstop or one-stop itineraries.

Returns:
    A ranked, paged list of flight options — airlines, routes, prices, and a link.

    Cash prices only. This tool does not currently return award (points/miles) pricing
    for flights, so do not state or imply a flight's points cost from these results. If
    the user asks how many miles a flight costs, say that award pricing is not available
    here right now and point them at the airline's own award search. Hotel award pricing
    is unaffected: the hotel tools still return points rates and cents-per-point.

Returns:
    Formatted list of guest reviews with author names, ratings, and review text.

Returns curated hotel recommendations based on the user's preferences, recent searches,
popular destinations, and upcoming holidays. Great for when the user doesn't know where to go.

    Travel suggestions with preview hotel results.

Args:
    booking_id: The booking ID or confirmation number.

Each profile has a selectable Profile ID, which prefills the guest name, email, and phone
at checkout so the traveler doesn't re-enter them
to prefill the guest details — the same "book as <traveler>" selection the website
checkout offers — instead of collecting name, email, and phone field by field.

Requires a Gondola account (API key).

Returns:
    Formatted list of travel profiles with IDs, or instructions to add one.

Returns the user's loyalty programs and elite tiers, home airport, preferred airlines and
cabin, preferred hotel chains, typical trip patterns (business vs leisure, budgets, frequent
destinations), and any preferences they've stated or that have been learned from past
conversations. Call this once at the start of a travel or planning session and weigh it across
hotel, flight, and car recommendations — it is the single best source of who this traveler is.
For raw evidence from actual past reservations, routes, hotels, airlines, or flight seats, use
get_past_trips.

Requires a Gondola account (API key).

Returns:
    Formatted travel context, or instructions to build one.

Use when the user shares a durable preference, like, dislike, or trip experience that should
inform future recommendations — "Always takes a window seat", "Prefers boutique hotels over
chains", "Vegetarian". Don't save temporary logistics like "my flight lands at 3pm".

Saved entries come back from get_traveler_context in later sessions, which is how a preference
stated once is still known next time.
