I am so happy to have found this thread!!!
I am Pooh sized! Currently I am 5'4", 275, size 24. I have recently lost 30 pounds on Weight Watchers and plan to lose a lot more by the time I hit WDW in November 2013!!!
I go to
Disneyland about once or twice a year and never have any issues with rides. At my very heaviest, I could not ride Mullholland Madness as the lap bar would not go down, but have had no other issues.
My favorite theme park shoes ever are
Crocs! I used to own 6 pairs, but sadly I found out I am alergic to them and can no longer wear them

So I am on the hunt for comfy, yet durable flip flops. It sounds like Teva's might be the way to go.
As far as clothes go, I used to have to buy exclusively online as nothing in the stores fit, but now I shop at Avenue and Wal Mart, a lot! Online I love Woman Within and Old Navy!! I just bought a new bathing suit for this season at Wal Mart. It is two pieces, shorts and a top and the top has underwire, which I need for the girls! I love it and it was $27 total for both pieces! I have also had good luck finding clearance items at Kohl's recently!
I am really nervous about all the walking I will have to do at WDW, but like I said I should be a lot lighter by the time I hit WDW, if WW keeps going well! Plus my exercise of choice right now is walking so that should help.
Is it hot in November? I hate the heat!!!
Again so glad I found this thread and I hope to get lots more ideas! I've only read through about half of the thread so far!!!
