re: Santorini Greece

Stay in Oia in a place with a private pool and view. Settle into cocktails as the loads of cruise ship people use their sharp elbows to push each other around as you watch in the comfort of your private balcony. Laugh at the line of people waiting to take Instagram pics by the blue dome. It gets very busy right before sunset but the mornings and evenings are very pleasant.

Hike down the path to the water. Swim out to the St Nickaolas chapel and jump off the ledge.

ETA: pro tip. If Santorini is your last stop, fly from Santorini to a major European airport. Santorini > Amsterdam is a nice side trip before the long flight home instead of backtracking through Athens
