DD and I stayed at BLT. I think the monorail was very nice to use. Only mishap that happened was that we weren't paying close attention to the signs on the way back from Epcot and got off the monorail from Epcot at the transfer hub, went down the ramp and back up the next ramp. We were busy chatting and suddenly realized we were on our way back to Epcot!
Almost did this a second time until we asked a cm if we were on the right one. He said no and we had to go down the ramp against oncoming people and walk a little farther to the ramp under the sign that said Resorts...
I don't know what we were looking at that led us to the wrong one. We've never stayed at a monorail resort before and usually have DH and my boys to follow..
Friends staying at Pop said they had to wait 1 and 1/2 hours for the bus after the race and it was VERY hot in the sun!
The monorail was a little bit of a walk from where you end because you have to go back to the front of Epcot, but it's really not a big deal.
Note about BLT - the night before the marathon, we went to bed at 8, only to be woken at 10 to the BOOMS of Wishes!! We had MK view and could also hear the ferry boats honking and the train whistling. Not a wise choice for the night before the marathon I guess
, but great for Sunday night when we just couldn't get ourselves to the park like I had hoped.
