Really glad to hear you had a good trip surfergirl !
I went down there last November to do the exact same thing ... flew all the way from Thailand to Hawaii, across mainland U.S.A. (never again with United Airlines - they just rip you off for luggage something unbeleivable and **** service in general) anyway, finally made it to the Caribbean, only to find one very stressed out skipper/mate and we both mutually parted ways ! What a big dissapointment it was ...
If I had of known about that company (Caribbean Kitesurfing) it would of been great (ended up back-tracking to Maui which wasn't all that bad) ... ****, us$650/week is a great deal ... otherwise, the Caribbean can be very very expensive ...
What time of year did you go ?
Got any pics ? (good idea to post 'em on Picasa via gmail or something similar)
