It will be out of season so alot of the nice places are closed at the moment. The museums in down town are nice though...visit the main art museum...I was there two years back and it was pretty nice. Also, there is a bug museum as well which was great...but I'm not sure if its open at this time or not.
Depending on how old you are, you might want to hit some of the clubs there too..they have nice clubs in down town
