My family and I stayed at WL for the first time this past June. We had visited it many times, and had always wanted to stay there, but never could (too expensive) But last year we joined the Disney Vacation Club, and, of course, just recently they built the WL Villas. Very nice part of the resort, btw. Go check it out when you go! It's fun to explore the place...it's very secluded!
I really don't remeber having to go to TTC to get to Epcot. I don't think you have to. I think that's only if you want to get to the MK by bus. there is also a Daniel Boone bus and a Davy Crockett bus (i think...) i believe those are for Downtown Disney and the water parks. for some reason those buses stop running at 4pm. but as for the timing, they're pretty much like all the other resorts. the only trouble we had was the morning we went to Epcot. and the only reason we had trouble was because i had left my ticket in the room. my sister and my dad went on into the park, and me and mom waited around forever for a bus to take us back to WL. for some odd reason the buses don't go back to the resorts in the morning...i have no clue where they go! after about 20 or 30 minutes of waiting, an empty bus came (one of those brand new buses that have some of the seats elevated.) that was kinda cool actually! having a big bus come just to pick up me and mom!
the boats are fine too, as you remembered them. they usually have several going at once, of course, so it usually doesn't take that long. and heck, sometimes you have to wait just as long, if not longer for a bus!!
You'll LOVE staying at WL though!! there's so many places to explore in the lobbys...sitting areas, balconies. and definately go on the nature trail if you haven't already done that! it's so peaceful! and, if you haven't already eaten at Whispering Canyon Cafe, that's definately a must! You'll have to tell us all about it when you get back!! oh, and before you leave your room, make sure everyone has their tickets into the parks!! ;-)
