  1. BellPlan a long weekend for Elio and Malik: from Port Avalon to Quillon, on to Fenwick Harbour, and back home. Friday 2026-10-30: fly Port Avalon to Quillon, leaving at or after 12:00 Port Avalon time (Elio works until noon) and landing in Quillon by 20:00 Quillon time for a dinner booking. Saturday 2026-10-31: fly Quillon to Fenwick Harbour, leaving no earlier than 10:00 Quillon time and landing in Fenwick Harbour by 18:00 Fenwick Harbour time for a concert. Sunday 2026-11-01: fly Fenwick Harbour to Port Avalon, landing in Port Avalon by 21:00 Port Avalon time. Malik checks one bag on every flight, and they want assigned seats together on all three. Book one hotel in Quillon for Friday night and one in Fenwick Harbour for Saturday night (1 night each), each one they can still cancel for free 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 $1505.00 (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.
