This is my opinon on off site guests using Disney buses. At times it was annoying & here is why. A few years ago when the Contemporary Resort would have their bus to Downtown Disney, it would only share with the TTC & those guests would get on from there was off site guests. How did I know they were off site guests? When going back to the Contemporary the bus would always stop 1st at the TTC & everyone but my family would get off the bus. So these people were obviously going to their cars, because at 10:30 & 11:00 PM the only guests who are there have to be off site guests going back to get their cars. What was annoying is sometimes we would have had to stand all the back from DTD & only got seats when everyone else got off at the TTC. Yes I know we could have waited for another bus, but the Downtown Disney - Contemporary bus takes forever, my family & I did not want to wait another 25-30 minutes for another one. The other thing that was annoying is if these off site guests had their own cars, why could they not drive them to Downtown Disney? It would save them a lot more time then leaving them at the TTC & taking the Disney bus back to get them. Thankfully the Contemporary bus now shares with the Polynesian & Grand Floridian, when going to Downtown Disney, this way we did not have off site guests taking our seats & if that sounds selfish & rude, sorry but that is the way I feel about this.
Also I don't remember reading anything in WDW books that says you need to have a valid park ticket to use WDW Transportation. All I remember reading is WDW Transportation is a free perk for onsite guests, so if that is what it's meant to be how can you call it that if off site guests can use WDW buses & etc? So I would like to see writen proof where it says you can use it with a valid park ticket, eventhough we all know bus drivers & CM's who let you on the Monorail never check for them.
