Hi there, Lisa!
Downtown Disney is currently undergoing the largest expansion in its history! In fact, I visited some of the new stores that have already opened in the Marketplace and they're fabulous!
As of right now, there is one location at Downtown Disney for the buses. It's located on the Marketplace side. Of course, things could change by the time you arrive at the Walt Disney World Resort so I definitely recommend checking back as your vacation approaches.
I always recommend allowing up to 90-minutes when you're using the
Complimentary Resort Transportation; especially if you have an
Advanced Dining Reservation to get to. You never know if there could be any delays at all and you'll want to allow time to walk from the bus stop over to
T-REX.
I hope this helps! Thanks for stopping by, Lisa, and please let us know if we can be of further assistance.
Wishing you and your family a Pixie Dusted vacation!
