Too many unknowns.
Are you taking DME? If so, you can't be sure when your bus will leave or how many stops you will have to make.
Are you on your own for transportation?
Are you checking any luggage? If so, (and DME isn't collecting your bags), you have to build in time to take the monorail to the main terminal and then get to the baggage collection area and wait for your bags. Total time there is a cap shoot.
Frankly, the only way I could see you getting to TL by 11:00 would be if you didn't have any checked bags and you rented a car through an express service like National's Emerald Aisle, or if you took a cab. You could go straight to POR, check in, and then take your cab or rental car to TL. But if you are taking DME to the resort and then a Disney bus from there to TL, I just don't see 11:00 happening.
