We spent most of our time at the MK and we stayed at the Contemporary. Couldn't have been happier with the walk over to the MK, it was very nice when pushing a stroller to not have to load/unload from transit as much. We took bus/monorail to other parks but never spent much more than a half day at those. Stopped at the hotel to rest after the other parks and then walked over to the MK if we were up for it in the evening.
