This past week was "President's Week", a vacation for many schools to commemorate President's Day, winter break, or whatever you want to call it. This week sometimes sneaks up on people at Disney World, as either they don't realize so many schools are closed or just don't think of it as a "big" holiday, thereby assuming that crowds will be lower. This is assuredly not the case, and President's Week is often one of the busiest weeks of the year at the parks, right up there with Christmas week, Thanksgiving and Easter/Spring Break.
I wrote about this a bit last week, as Genie+ sold out on consecutive days for the first time ever. There are some caveats to that, as Genie+ has only been in existence for about a year and a half, and Disney is constantly making changes to "improve the guest experience" (or so they say). The short version of that post was that it wasn't necessarily alarming that Genie+ had sold out, and that this week would be very busy regardless.
