So the transportation is good, but I have to disagree with some.
I have had to wait for the second boat.
I have had to wait for the next bus (internally)
I have had to take "Alternate" routes (i.e. the bus to the Settlement, but then take the yellow bus to the Wilderness Lodge to catch another bus to the MK.)
I have waited 15 minutes for a bus at a loop and even longer for a bus to one of the other parks (at the Outpost).
Also it's not just about the bus/boat to the park, the return trip is a factor. If you are leaving at the end of the day (park close), it can be crazy getting out too. I have had to wait for the second boat leaving for the fort. I have even had to get on the Wilderness lodge boat to catch the bus there over to the fort. Sometimes, they only run one boat for the Fort AND Wilderness Lodge/Contemporary. A couple of times, the stopped running the boats (Weather related) and we had to wait for a Bus to take us to the Fort. The don't normally have a bus between the Fort and MK (Directly) so the wait was a LONG wait which sucked at the end of long day. But it happens.
And while this is not the norm, it does happen. We do usually get a golf cart, because we don't want to take a bus to the pool and walking, depending on where you may be can be just as long (or longer) as waiting for a bus (that is slow). Again, not disparaging the transportation, because mostly it goes very smooth, but like anything else, it's no perfect and issues do happen.
