Where should I go on vacation?

So my mom and I (I am 14) are planning on going on vacation for about a week and a half too two weeks depending on where we go. We both want to go somewhere with beaches and pools. It has to be hot out. We would like the place to have many cultures and places for us to visit and hike through. We are looking to spend under $7,000CA, but that doesn't include spending money :)

The US or Caribbean would be ideal.. But any suggestions help! Thanks!
