I've never stayed at WBC before (first trip in 28 days!!!), but I've gone to MK via the TTC before, and for us, it wasn't a big deal. You take a tram from the parking lot to the monorail/ferry. Ride the monorail to MK. I'm sure that things can go wrong and make that not such an easy thing, but I don't think it would normally require 2 hours to get from WBC to MK. It should take about 20 minutes to drive to MK from WBC, maybe 30 minutes from TTC to MK (and that is on the high side of average, I believe). I would probably be comfortable leaving between 7:15 and 7:30 (I like to have plenty of time). As I say, I've never been to MK from WBC, so maybe others can chime in with more experience. For me, though, parking at the TTC and taking the monorail over to MK was no big deal--certainly easier than dealing with Disney buses. JMO.
