I was able to get a great rate (through Marriott's pricematch) on this property for our July trip. We usually stay on-site but the rates are too high right now. The Marriott seems to have great reviews on Tripadvisor but no one really mentions the shuttle. I am assuming it is a limited shuttle (a few pick-ups a day). I think someone may have mentioned the shuttle going to Epcot and then you have to take transportation from there. We do plan to have a rental car but I was just curious able the shuttles they have.
