Hi Brides

We are getting married March 21, 2015- I know its early but we are paying so need to budget and plan out expenses. Which island is good to go to during March-April? My fiance and I would love to do a booze cruise and fun things but also relax and not be with a bunch of spring breakers. Looking into Antigua, Barbados, Grenada, St Maarten, St Lucia.. Open to suggestions and tips!
Thanks and happy planning!
