We were at WDW for 10 days early December. Saw all the parades and loved them all. But as I look back at our Trip Album I was amazed at how many more pictures there were of the Animal Kingdom Parade. MGM..is simply cars and characters...nice, but nothing outstanding. AK's parade is a site of artistic creativity....huge, towering displays....colorful, exciting, and something much more difficult to put on. I wouldn't hesitate to say if only one...go to AK. But, as others say, skip the ice cream and go to both. Gee.....you can get ice cream at home. You will love it I'm sure. Good luck.
