My 2.5 yr old DD is VERY tall, she was outgrowing her stroller. I went to a children's consignment store and got one (Graco, I think) that is HUGE!! The wheels are much bigger than her old one, and she can recline and still not touch her head on the canopy!!! I paid $28 for this!! That is quite a bargain compared to the WDW world prices. Plus, it has a really large basket for carrying things, a really nice "meal tray" with her own cup holders, and two cup holders for us.
I LOVE strollers!!! I think my DD will be in one for a LONG time, if I have ANY say in it!!!
Anyway...look at the different ones, and have your child sit in them. Some are MUCH larger than others. The bigger the wheels are, the better, and if you can get both front and back wheels that rotate, it is easier to steer (although those tend to be expensive). Just remember, pushing around a 45 lb child is not going to be like what you remember. My DD is 27lbs...and, sometimes the stroller can be a bit difficult to manuever!!
Have fun shopping!!!
