  1. BellPlan a long weekend for Priya, Ines, Elio and Theo (4 travellers): from Oakhaven to Thornbury, on to Ashby Cross, then Kestrel Bay, and back home. Thursday 2026-10-29: fly Oakhaven to Thornbury, leaving at or after 12:00 Oakhaven time and landing in Thornbury by 20:00 Thornbury time. Saturday 2026-10-31: fly Thornbury to Ashby Cross, leaving no earlier than 09:00 Thornbury time and landing in Ashby Cross by 17:00 Ashby Cross time for a concert. Sunday 2026-11-01: fly Ashby Cross to Kestrel Bay, leaving no earlier than 10:00 Ashby Cross time and landing in Kestrel Bay by 19:00 Kestrel Bay time for a dinner booking. Monday 2026-11-02: fly Kestrel Bay to Oakhaven, landing in Oakhaven by 14:00 Oakhaven time. Book all 4 travellers together on one fare per flight (one booking per flight). Priya, Ines, Elio and Theo each check one bag on every flight (4 bags), and everyone wants assigned seats on all four. Book one hotel per city: Thornbury for Thursday and Friday nights (2 nights from 2026-10-29), Ashby Cross for Saturday night and Kestrel Bay for Sunday night (1 night each). Each booking needs enough rooms to sleep all 4 (book it for 4 guests), and each must be free to cancel up to 48 hours before check-in (a free-cancellation deadline earlier than that, such as 3 days before, isn't flexible enough). The budget is $4185.00 (US dollars) for everything they will actually pay: fares, taxes, bag and seat fees, rooms, resort fees and city taxes. Book it all, then add the trip to their shared calendar.
