Looking for a beach trip, no passport

[Keyser.]

I'm getting short-term braces to deal with a little smile defect I've been wanting to fix, and I basically want to just go to a tropical location by myself and hide out for a while.

Problem is I don't have a passport (I'm American btw, and I will get a passport eventually but won't have it in time for when I want to leave). Where can I go? Reasonably cheap would be nice. Internet for poker purposes is a must.
