I did Animal Kingdom for my 50th birthday and had a great experience. I booked the first slot of the day, so most people were doing the "Flight of Passage 5K". That did mean that I was strongly cautioned against using Pandora for my site - they said it was my choice, but in their experience, even with the second CM to keep people out of the shot, I'd get about half as many shots. So we did Asia and around the Tree of Life. I'd post the link to my album, but it's on FB and those links aren't permitted on here.
