Looking for Suggestions

So, ever since I've started recovering from my bronchitis+gastroenteritis health crisis, my life has been moving along. It consists of the same old routine: get work done, do the laundry, run errands, make Shabbat plans, blah blah blah.

One thing I'm learning about myself is that it helps me a lot to take a short but real vacation -- a going away and staying somewhere else and seeing new things or sitting by the beach or pool vacation-- every six months. Since I work for myself and don't have any kids, I can do that.

But money is an issue.

So, help me out here. I need to plan something fun for 3-5 days, something that will take me out of my normal routine, but which is very cheap.

Any ideas?
