Hi Kristal!
Welcome to the Disney Parks Moms Panel.
It's so disappointing when our flight times are changed, especially when we have planned everything around them. If you arrive at Orlando International Airport at 1.30pm, and have a dining reservation at
T-REX for 3.15pm, I think it will be tight, if not impossible to make that on time. However, if everything goes to plan, your plane arrives on time, your taxi is waiting and there is no delay with checking-in at
Disney's Wilderness Lodge and Bell Services, and your taxi waits for you to take you to
Disney Springs, you might be lucky. I personally would not risk it, but would try and move my reservation, +1 hour if you can. I know this is a popular restaurant, and I don't know your arrival date, but if you are looking a few weeks/months ahead, it is quite possible that you will be able to make a later booking. Keep checking, as cancellations do occur all the time. If you only have carry-on luggage you could have your taxi drop you off at Disney Springs (as you will drive past that on your way to Disney's Wilderness Lodge), but if you have anything larger than that you will have to go to the Resort hotel first. I'm sorry I can't be more positive about this, but I don't want you to be too late, or miss your reservation completely! Please know that there is a charge of $10 per person for anyone who doesn't show up for their dining reservation (this amount is subject to change). If T-REX is not available for a later time, there are many other
restaurants at Disney Springs you could try.
Rainforest Cafe at Disney Springs Marketplace is similar. Also, I thoroughly recommend
Whispering Canyon Cafe at Disney's Wilderness Lodge - this would be a really fun place to start your Walt Disney World vacation.
Please come back and visit us if you have any further questions. We will be happy to help you plan your magical vacation, and keep your eye on the
Disney Parks Blog for all the latest official news and updates on any events that may be happening during your stay.
