The short answer...in a perfect world...is, yes. However, there are so many variables that could alter that prediction. Let's hope your plane is not delayed, but in today's world this is a real possibility. Then, how long to claim your luggage....I've had positive and negative experiences with that in the past year. Then, how long do you have to wait for your particular Mears transport to get on the road. So....all that being said...if all goes well, there is no reason why you can't be in Disney Springs in 3 hours from landing. I really hope it all works out perfectly for you!!
