Help! Where should I go for spring break!?

i was going to Puerto Rico but its sold out coming back so now i can't :( im so sad but more importantly i have no idea where to go now! i do not want to go anywhere in the US. i've been to most places in the Caribbean so if you have a place that has nice resorts with a lot of stuff to do then tell me but i've been to the Bahamas, Jamaica, st. martin, St Barts etc. and i need somewhere with a beach but no secluded areas por favor (:
