I actually just signed up for this last night! I didn't know what to expect. This is a program that you download. Word to the wise -- my security picked up spyware. That's easily ignored though. Also, please be aware that this is a no-frill program. I loved Tour Guide Mike for my first few trips, but this is not like Tour Guide Mike -- there are no photos and no commentary or advice.
All of that said, it's pretty cool. You select the park and date and times that you want. They may not have all dates loaded yet, so keep checking. In my case, they didn't have Magic Kingdom for the day I wanted to go yet. So, I chose Epcot Future World arriving at 12 noon and getting in line for my last ride at 9. You can also figure your dinner/lunch breaks into the touring plan as well. You also have the option of choosing more walking/less standing in line (ie, running from HISTA to TT to get a fast pass, then going back across for Turtle Talk) or more standing/less walking (assuming it goes in some kind of order, didn't try this yet). You select individual attractions and it plugs them into its program and prepares the plan you requested. The Epcot Future World one made sense...The MGM one has us with 5 hours of free time in the middle of the afternoon, but I only put rides, and no shows in.
I'm looking forward to playing with this more. For a family that's Disney experts, I'd say take this over Tour Guide Mike. For a family getting into the magic for the first time, I'd do both, or do this with Unofficial Guide or something.
I'll be at WDW Aug 26-Aug 31 for Free Dining (Yay!), so I'll let you guys know how it works when I get back.
