Somewhere warm but not boiling hot (28 degrees maybe). Warm sandy beach. Wake up early and go for a walk along the beach with DD, chatting and generally messing about. Back to get DH up for a lovely breakfast, poote about. Spend some of the day swimming, snorkelling, scuba diving with DD while DH acts as lifeguard and beach-towel-holder-down. Lunch of many lobsters. Nap and swim in the afternoon.
Evening is a soft night under the palms, eating snacks and drinking rum drinks. Some other friends and family would magically show up for this bit. Get a little silly, play some games and drift off.
But ask me tomorrow and it would be different.
