We did the FTP 7-15 to 7-22, booked on a whim only five weeks ahead. The parks weren't nearly as crowded or hot as I thought they would be. Use fast pass, EMH, AC, breaks and the mister fans. The components of the package are your resort, UPH and a framed Mickey Philharmagic print with pin. The dimensions of the box it comes in are 15" x 18 1/2" x 1 3/4". Since we flew, I had to get very creative to fit it in my suitcase.
The UPH are great--for the first time we visited Disney's Wide World of Sports. Now DH says the Tampa Bay Bucs cheerleaders are his favorite "Disney characters"!
Toward the end of our stay, the crowds seem to pick up. The FTP is bringing a lot of first time visitors to the parks who aren't familiar with the tips and tricks. That may also account for a little of the crowds/lines.
