We were staying at the Beach Club, so we walked to Epcot and met an event guide at the International Gateway. She escorted us to our DP. We got a charter bus for our guests because they were spread among four different resorts, but if I'd been thinking, I would have tried to get them all to stay at just 2 resorts so we could do a round-trip bus. We didn't want to leave them to make their own way to Epcot b/c most of them had never been to WDW before.
Here's the skinny on transportation:
There are three types of trips: one-way, round trip, and charter. One-way trips are only available on Disney property and travel just from Point A to Point B. Round trips travel from Point A to Point B and back to Point A. Charter transportation can make an unlimited number of stops but must be hired for a minimum of three or five hours, depending on vehicle type.
You may be able to save money and avoid having to charter transportation by adding one stop to a one-way or round trip for $20$50, depending on the vehicle type. For example, if all your guests are staying at just two Disney resorts, you can hire a one-way motor coach and add an extra stop. However, trips with more than two stops or a transfer that lasts longer than 15 minutes automatically become charters. So if your guests are scattered among four different resorts, you will be required to charter a motor coach for a minimum number of hours that may be longer than you need. Therefore, its important to consider transportation when youre setting up your room block.
I made a chart of the various types of transport and their capactiy and the cost, but it doesn't copy and paste into the post very well. Also, the prices may have gone up or down by a few dollars, depending on what Mears is paying for gas these days.
