I go to Mykonos almost every summer, this is my best place to relax in the beaches and to do the best clubbing of my life!! All Greek islands are beautiful but
Mykonos has something special, I believe. It is probably the feeling of the people who come here to enjoy and spend the night out and laugh loudly and have fun!!
My best beaches are Paradise and Super Paradise, although they get so crowded. I like crowded beaches (it is the best way to meet new people!!!). Cavo Paradiso is the best club far, and some small bars in Chora are also cute and fun.
In Mykonos, you stay out day and night. You go in the room only to have a shower and change and then you go out again. Some days, you don't even need to change your swim suit!! Such a nice island if you are 20!
