Where to begin!!!
1) Moderate priced suite rooms. Traveling for a week or two with children, DM and DD prefer our own room. There are many really nice off site places like Summerfield, Sierra, Buena Vista, etc. suites for under $100 off season. Something similar on site would make the decsion easy for us, we would stay os site every trip.
2) Animal Kingdom and MGM have so much potential. There's no reason MGM couldn't have more high end thrill rides like Islands of Adventure. Teens love those rides, and Rockn Roller Coaster and Tower of Terror or fine, but they're not the wild coasters. THey could also do more there with the studio aspect. The movie ride (whatever its called) is a cheap version of what Universal did 20 yrs ago. Cmon Disney you can do better than this. Same thing for Animal Kingdom. This is DISNEY! I expected to see a world class zoo with a theme park built around it. Instead a few animals and a few rides.
I guess the point is this. MGM is Universal Light and AK is Busch Gardens Light. Now that's fine...except when you pay just as much to go to these parks as you do MK.
3) More consistent and publicized hours, electric parade, etc, etc. Seems like you never quite know what will happen when. I can adjust, but it drives my DW crazy.
4) Finally...you'll all love this one. EXTRA FAST PASSES for staying on site! Makes too much sense to even elaborate on.
