The trick to their bus service is to walk or drive to the North Depot for all parks except AK. That is the first pickup location and you will always get a seat by the time you leave the last depot. For AK walk over to south for pickup as that's where they pick up first for AK.
I would recommend you ask the bus driver to make sure they haven't changed the first pickup locations, but they've been that way a long time. Also, if you have waited more than 15 minutes for a pickup for a particular park, you can simply tell any driver who comes by, and they will call for a pickup.
They did that for us a early in the morning when not as many busses were running for a non EMH parks. That comes in handy when you have an early dining reservation (within reason). We didn't even have to ask the first time, the driver asked who we were waiting for and then called to make sure one was on the way. Some of the drivers are so very nice and helpful, but we did have a few bad ones. We put that up to dealing with so many, not necessarily nice people for weeks and months on end.
We always make it a point to give the cms, drivers, etc a smile and a hello. It might change their attitude for the whole day.
So if the bus pickup was the only problem you had with POR, then that is easily solved and could save you a decent amount of money over WL. If money's no object, then I would trust the ones who have said they would pick WL.
