I apologize if this seems repetitive but I would love some direction...
We would like to take our 14 and 4 year old boys on vacation in July. We are unable to vacation at another time of the year due to sports commitments. We would like to be in the US, Central American or carribean. My younger son is happy with a pool and a beach and we would really like to do a great vacation for our older son who loves the beach and outdoor sports...zip line, snorkle etc.
We have been considering Costa Rica....we are aware of the weather there in July and not sure if the JW marriott is so great...worried that most places in general are just going to be too hot....anyone have a suggestion? We would like to use marriott points if we could....

Thanks!
