As it was a bit off season (early September), nightlife on Mykonos wasn't as wild as we expected but we enjoyed the sea the most. This was the most appealing part of the island for me. The relaxed athmosphere and the lovely inhabitants of the island helped me have a great time. Food was not th best I've had so far in Greece, still it was satisfactory enough. Don't bother taking a taxi or waiting for the bus on
Mykonos , just rent a small car for as long as you stay. Do it instantly when you reach the island and get a discount, travel around the island as much as you can, freely, since you have chance to get lost :) Especially go see the beaches down south. Super Paradise and Elia are a shore to the eye and have very relaxing water.
