We went about a year ago and stayed in a Comfort Suites. I cannot remember the address/location. I know we were very close to Animal Kingdom because we could see one of the rides from the pool area. It was a fabulous hotel. Had a nice pool, rooms with mini fridge and microwave. (Just enough room for storing snacks for the parks.) It offered shuttles to all the parks. Although, when they offer these shuttles they only go at certain times to certain parks. So, say that we wanted to go early in the morning to Epcot. We would have to take the shuttle that left at the time that was offered but it was maybe going to a different Disney park. Then we would have to take a Disney shuttle/ monorail to the park that we wanted to see. The same for going home. We would have to allow time to make it to the correct shuttle to get back to our hotel. That was the only complaint. It also had a continental B-fast. It was actually really nice because EVERY day they had hot items (biscuits/gravy, eggs, sausage, etc...) AND they had Mickey Mouse Waffle Makers. That was one of the fun memories that my kids remember, every day I would make them their own Mickey Mouse waffles for breakfast!
The shuttles are the only complaint I had about staying "off site". (They offer shuttles that go to all the parks that leave every 10 minutes.) If you will be needing to go back to hotel during naptime, etc then this will need to be taken into consideration. I would request to see a copy of the times/locations for the shuttles before booking the hotel. When we booked with the hotel they made it sound like they were constantly leaving/returning, when in reality it was only a few times in the morning and a few times returning. Also, one of the nights we stayed after hours for trick or treating, we had to take a taxi home because the latest shuttle left at like 8pm or something.
Sorry this is so long, I wanted to be thorough! Have fun on your vacation. We had a blast and CANNOT wait to go back!
