No it is not a waste of money. Grand Floridian is not far from Magic Kingdom, compared to Polynesian's location. It's pretty much like Contemporary in terms of location right by the park. When you're staying at GF and you board the monorail to get to MK, the ride is the shortest, since the park's right there practically. However, going back is different, where you have to go through the other two hotels & TTC before getting to GF, unless you decide to take the water taxi. This is basically just offering another possible way for guests at GF to get to MK and back to the hotel instead of relying on monorail or water taxi--the same as the guests staying at Contemporary, where they can use the monorail even though it would be silly to go through all that when they can just use their walkway to get to MK. Plus this could possibly help alleviate the crowds waiting to get on the monorail. People going from MK to GF and vice versa can walk if they want instead of having to use the monorail/boat and everybody knows the monorails get super crowded at times. Anyone who complains about something minute like this is probably jealous because they know they'll never be able to afford staying at GF and so complaining about something that shouldn't mean anything to them makes them feel better. Otherwise I don't see why people think this is such a problem.
