Walking in Disney

My wife and I went with another couple to Orlando, Florida! The plan was to visit Universal Studios (to see Harry Potter), Sea World (to see the manatees), and Disney World (to see Mickey Mouse). The plan was almost successful.
We went to Universal Studios the first day. We had to walk maybe a half mile to get from the parking lot to the Harry Potter exhibit. When we first entered Universal Studios proper, it wasn't very crowded. But, as we made our way through Dr. Suess Land, Sinbad's territory, and several assorted retail booths the crowds grew. By the time we got into "Hogwarts" there were many people who were loud and pushy and trying to take pictures. It seemed chaotic. When we got to the ride itself we realized there was to be a wait of at least 90 minutes - I think ours was 2 hours slow! But all-in-all we got our walking in for the day.
When we went to Sea World we were less crowded and did more walking. I think we spent 4 or 5 hours each day walking around the two amusement parks. We did not see any manatees, though. Their habitat was being rebuilt and they were staying in their "winter ponds." However we did see Shamu and other "Killer Whales" perform some fantastic acrobatics. We walked through several rooms of aquariums. We walked through a glass tunnel where you could see the sharks, stingrays, and other fish swimming above and around you.
The next day we decided to visit just part of Disney World - Downtown Disney. It is mostly shops and didn't cost anything to walk around and look at all the things for sale. And walk we did! We walked through Lego Land where we saw dragons and knights built out of Legos. We saw Snow White with some of the dwarfs and tourists built out of Legos. It was awesome! We walked through the Christmas Shop where one could buy all the Disney Christmas Tree ornaments available. We ate lunch in the Rain Forest Cafe, which is absolutely wonderful. It has columns of aquariums filled with bright, colorful tropical fish. Later we went home and collapsed.
On Friday we went to Epcot Center. It is so wonderful! We walked around looking at all the fountains, streams and gardens. We walked through the different "countries" where we saw the buildings of the Aztecs, Chinese, and other cultures. We must have walked 3 or 4 miles because we spent about 8 hours touring the park. We saw a video about sharing our resources with the rest of the world and how our actions affect the entire planet. We rode a simulator that taught how fossil fuels were made and how we used wind, the sun, and water to create electricity. We need them all to generate enough electricity and keep the planet healthy. Another ride gave us a glimpse of the future and all the tools (or gadgets) that would be at our disposal.
Wow! Now that is the way to get your walking in! We rode just enough rides to give us some rest. Oh, and I did stand in line for about an hour to get my picture made with Mickey Mouse. It is fun being a kid again.
Where have you been to make your walking exciting and adventuresome?
