Combi makes great travel strollers that have a weight limit of 55 pds. They are very light weight, easy to fold, and have a carrying strap....great for the buses at WDW.

Shop around online...I found both of mine on sale because a newer model was coming out.
Maclarens go to 55 lbs and are great for travel.
BOB and Baby Jogger also have high weight limits but not as light to travel with, with the exception of the Baby Jogger City Mini which I definitely would suggest you check out- it's a WDW favorite among many on the boards.
