We love Les Saintes but have only ever visited on our boat so can't help with accommodation.

Great restaurant... Ti Kas La. Chef Phillippe Dade is excellent and his menu contains some amazing dishes. Been many times but sadly not in the last two years.

Liquor store... It's France. Of course there is a liquor store <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />

Have a great time, very envious.
