I'm also interested similarly in finding out when President's Week break is. Birnbaum's says President Week is packed, but is President's Week actually that week (Feb 17-23) or all the weeks around then? By us (Michigan), 2 years ago my kids had that week off, last year they had the week before, and this year the week after, which is when we're coming. Various school districts seem to give any week in Feb, but is that just a Michigan thing? We're arriving the 19th which is technically during "President's Week" - will crowds be much worse the first few days than the next week, or will they all be about the same? Thanks!
As far as people coming from this part of the country, we ALWAYS get the week after Easter, but I know the Chicago area gets the week before! Since Easter isn't until late April this year, this shouldn't affect your planning!
