I guess I should have been clearer but I think the question was answered anyway.
When we have stayed at the Yacht Club on Disney, I was very frustrated with the boat to MGM because it was so slow but walking seemed like a waste of energy for that distance. Plus it was near impossible to make opening by the time the boats got started and then creeped on over to MGM. However at Grand Floridian or Polynesian I looked forward to a nice quick boat ride over the MK and preferred it to the monorail, which I also love. So we are trying to decide between the HRH and PBH and I am concerned that the walk might be little long (very hard to tell from the maps or satellite photos) and the boats might be slow if we chose PBH.
