We stay at the Hilton at DTD. There are 8 hotels in that area and they have a seperate bus service from Disney but it now only does one side of the road so a maximum of 4 hotels (they collect and drop off at the ones at the DTD end first). They run every 30 minutes. Personally we have never had any problems with the service and find it more than adequate. You haven't said where you are staying but there are things you can walk to at both ends of the road. DTD is 5 mins from the Hilton - you need to add 5 mins for each hotel the further away you go. At the other end of the road is the crossroads shopping centre which has a supermarket and numerous resturaunts. There is also a minigolf place. It is a 20 minute walk from the Hilton. There is a walgreens another 10 minutes further on foot as well as tourist type shops and more resturaunts.
The lynx bus (50) now runs along hotel plaza boulevard which runs to seaworld and downtown orlando.
Off there in 21 days and counting!!!!
