We were there in February and had no problems with the shuttle. Granted, it does not operate as often as the Disney hotel shuttles, but they come about every 20 minutes. They do not pick up from each building however, so you may have a bit of a walk, depending on your room location. We were equidistant from the two stops and it never took more than 5 minutes to get there to the bus stop. If you are looking to return to the hotel mid-day however, you might have more issues as the shuttle drivers take lunch breaks from about 12:30 - 3:30. If you will be staying much of the day, you shouldn't have any problems. Animal Kingdom had the fewest returns, only one at 4 and one at 6pm. Most of the other parks had returns throughout the day. I do have the schedule from Feb, so I'll try to take a photo and post it.LadyBeBop, I hope someone answers your question, and I'm glad you bumped... I am staying at WBC in two weeks, and I am very concerned about the shuttle schedule. Our party also has too many for one car, and it's expensive to rent a van. I don't want to have to rent a van, but I also want to know (before we go) that we'll have adequate shuttle transportation.
I'll post my shuttle schedule when I get down there. I keep hoping someone who is there now will take a photo and post theirs.
I will call WBC on Tuesday and ask if they can email or fax the current shuttle schedule... I called a couple of weeks ago, and they said it could change and that I should call back at a later date.
