getAvailableDates
ChatGPTPrice calendar for Fattal (פתאל) hotels in Israel: for each check-in date in a window, the available hotels ranked by their lowest "from" price. Use when the user explores when/where it is cheapest ("when is it cheapest to go to Eilat?", "show me a price calendar", "cheapest hotels in November under 2000"). INPUT: destinations, fromDate..toDate (window capped at 31 days), nights (REQUIRED, fixed stay length so dates are comparable), adults (one room), optional children, optional maxPrice (NIS budget filter). OUTPUT: per destination, a calendar entry per date. Each entry lists that date's hotels cheapest-first (fromPrice in NIS, taxes included, single room at the requested occupancy); soldOut:true means nothing is available for that stay length/occupancy (or none within maxPrice). NOTES: prices are the public "from" price (the member-club / deal price from searchHotels is lower). Israel hotels only; other destinations return an empty calendar with a note. infants do not affect price. For an exact multi-room booking with full room/board detail, use searchHotels.
