Pressing Question

I have semester break coming up in a little less than a month. I get a week off, February 7 to February 15. I'd like to take a trip during that time. All things considered, it will probably be the most significant bit of traveling I do while I'm here. So the question is, where do I go? Things to consider: I'll be traveling alone, I only have a week, and my budget is somewhat limited. Here are the options I've come up with so far:

England (Bath and Stratford-on-Avon would be included)
Dublin
Stockholm
Lisbon

I'm open both to other suggestions and to comments on these possibilities.
