Lex, I've been thinking about that, too. I think if a school (W&L in your case) is definitely your first choice, it can't hurt to go both so you can show them you're really interested in going and so you can see for yourself what the school is like. I've seen some other people on here post about meeting with someone in admissions while they're visiting, and I think that also sounds like a good idea if you can arrange it.
