ratticus - I know what you mean, we have a friend joining us from Italy who is on a tight budget, so we are having to find creative ways around this issue, my children are geared up for theme parks, no way around that!
I don't think I've heard anyone not rave about DC.
I'll look forward to your trip report and how you felt about your villa and it's location. I'm already thinking next trip and we've not been on the May one yet! LOL
