We did a Contemporary Resort theme park view last October. The view was absolutely fantastic! I loved waking up in the morning and having a cup of tea on the balcony as I looked out on the Magic Kingdom. It was also watching the Electrical Water Pageant at night. It was also excellent being able to walk to Magic Kingdom and having the TTC be the first stop on the monorail when we were heading to Epcot. There were some negatives though. The elevator situation was a nightmare. They don't have enough elevators for the resort so you had to wait a long time. When one finally did arrive it was common for it to be too full. We ended up taking the elevator up just so we could definitely have a spot on one and then took it back down. For our family, we are very happy we did it and don't regret it, but we aren't planning on doing that again anytime soon. For us, we'd rather use that money towards something else.
We all love Wilderness Lodge. It is the most requested place when we discuss where we might stay on an upcoming trip. Just walking into the lobby is very relaxing. We all love the pool, especially the fact that is starts inside the lobby as a bubbling brook. You can also see the Electrical Water Pageant here, but with the growth of the trees, it is more difficult to see it from your balcony. You can easily walk down to the beach to watch it, though. We love taking the boat to Magic Kingdom. The captains are so friendly and make the ride enjoyable. Some will sing, tell jokes, or ask Disney trivia. Others will simply talk with you, but it is never a dull ride. Very beautiful and fun. On the downside, there is a lot of construction now and there is no longer any such thing as a woods view (personal rant: how can you have vies of the woods at Beach Club and not at Wilderness Lodge? Ridiculous). The counter service restaurant here, Roaring Fork, is also incredibly small for the size of the resort which results in long waits around breakfast time. Still, our family loves it here and would be more than happy to stay here at any time.
Polynesian is gorgeous. Transportation is also excellent because you can walk to the TTC if heading to Epcot or the monorail if heading to Magic Kingdom. Not a lot of negatives to say about it, but it has been forever since I have stayed here.
I have no desire to stay at Grand Floridian or AKL, so keep that in mind when reading my recommendations.
I'd recommend Wilderness Lodge first. Our daughter fell in love with it when she was 4 and has loved it ever since. My second recommendation would be Polynesian. If your daughter loves Lilo and Stitch, definitely look into breakfast here, as well. Third, I would go with Contemporary. After that, it's a wash between AKL and Grand Floridian. With AKL, the animals can be fun, but you have already stayed here twice and might want to change it up. Plus, it is close to Animal Kingdom Lodge but none of the other parks. Grand Floridian is beautiful and convenient to Magic Kingdom, but I just keep hearing the words that a boat captain at Wilderness Lodge said. He said that he loved doing the Wilderness Lodge boat the most, was perfectly fine doing Contemporary or Polynesian, but hated Grand Floridian. He then said that passengers make all the difference when it comes to his preferences. He left it at that, but I guess it just stuck in my head and makes me less likely to want to stay there. So many people on here, though, swear by the resort and seem like perfectly lovely people so I just really don't know. For me, I'd just rather spend the money elsewhere. If I wanted a resort that I thought was just breathtaking, much like Grand Floridian is, I'd go with Yacht Club or Beach Club since they are within walking distance to 2 parks.
