Hi, Burnie!
I couldn't be any happier that you wrote in with this question! I want you to know that not only can you have an amazing time, but you will be able to have the most amazing time ever!
As you may [or may not] be able to tell from my profile picture, I am on the "fluffy" side myself and it does not stop me from having the time of my life every time I step foot on Walt Disney World property! Here's the very best part. The Imagineers take these things into consideration when they are designing ride vehicles and seatbelts. There isn't one ride in all four of the major Theme Parks that I cannot fit on due to my size. There is a fantastic section on the AllEars.net website called "WDW At Large". If you type that into the search feature on the main page, click the top link on the list and you will be taken to a page where you can read trip reports, tips and tricks from other Guests. I found this extremely helpful back when I was planning my very first trip to the Walt Disney World Resort!
My most important tip for you ladies is to make sure that you wear comfortable shoes because you will be doing lots and lots of walking. Also, make sure you drink plenty of water because it's still pretty humid in central Florida in September and it's important to stay hydrated!
Be sure to order your
Free Disney Parks Vacation Planning DVD so you and your mom can get a little taste of all the magic that awaits!
Burnie, thanks for stopping by with your question and please don't hesitate to write back in if we can help in any other way!
Wishing you Pixie Dusted vacation planning!
