My DD never uses her stroller at home- not even when we go to the zoo all day. She might get in it for 5 minutes at the very end of a long day at the zoo, but that is it. She was 2 yrs 10 mths when we went to WDW a few months ago. She had absolutely no problem using her stroller at WDW. She let us push her in it quite a bit and when she was tired got right in and took naps. She also definitely understood when we were in a hurry to make a showtime or get to an ADR, and she would jump right in so that we could go faster. You just never know. I would definitely take it and try. I would say take your own, as I'm sure it is more comfortable than the WDW ones. Also, decorate it so you will be able to find it after you park it in the sea of strollers. We thought our stroller was unusual and we would not have any problems, but we saw several like it. The big bright ribbons we had tied to it really helped.
