STYLETHREAD -- LET'S TALK SHOP!

I want to take a solo vacation for spring break. I have been pretty stressed out lately and I just want to relax, plus, this spring break will be my last. I know it is kind of early to start thinking about March but I am a pre-planner. Anyways, I need suggestions on where to go. I have some requirements:

1. It has to be a safe place for a single girl to travel alone

2. It has to be in the U.S.

3. Can't be to expensive

But other than that it is pretty much anywhere. Any suggestions? Thanks
