It is usually a van that does accomodate others. When you go to baggage claim at the airport you will see the Mears Shuttle information desks set up (they are about every ten steps...can't miss them, yellow and black) and they will let you know where to go to get the shuttle itself. As far as going straight to the hotel or making stops, it depends on if they have other people in the van with you and where you fall on their list of stops (Vans only accomodate about 10 people, maybe even less so it is not going to be crazy and they generally take all Disney people together so if there are stops it would be at other Disney resorts). It can be right to the hotel or you might have to stop a few times a long the way. As for tipping, that is up to you, but generally the drivers are tipped.
