To Wiscon or not to Wiscon?

Following up rosefox's entry, I'm still undecided on Wiscon.

Pros:
- lots of cool people
- lots of cool programming
- great reviews
- know people who are going - fun can be had

Cons:
- weekend before our trip to England (though Memorial Day weekend, and time off can be had)
- plane tickets are expensive, and we should be saving for things, such as England
- hotel rooms?
- convincing Doyle he wants to come.

Discussion?
