I highly suggest New Orleans.
It is a very nice time away, with tons of activities to do. Even if you just wander around the Quarter, the time will fly. And every day and night is mardi gras on Bourbon, which is lined with strip clubs and $5 hurricanes stands that you can drink as you walk around the town.
If you want more sustenance, there is a ton of history in that city, and is a photographer's paradise.
It is a southern city, so also expect that refreshing, relaxing slow and take it easy vibe everywhere you go. The weather is in the upper 80's right now.
Depending on where you are, it is a short plane ride, and not very expensive either. You can get a very nice hotel on hotwire in the French Quarter for less than $60 if you allow 3 weeks advance planning.
