Will be renting a stroller for my five year old granddaughter. She will be doing some walking. Staying on site at shades of green. I'm wondering...just how "uncomfortable" are the "hard plastic" strollers that you rent in the parks? Just seems like this might suit my needs better so I don't have to haul the stroller on the monorail and busses. But honestly I just don't know which way would be better. We plan to stay late for shows and fireworks etc so she will be doing some stroller napping. Advice please?? Just can't make a decision.
