I am at a loss...take our double jogger, double regular or rent at the parks. I am really dreading taking/getting a stroller on the tram and monorail. I am traveling with 5 young children which includes 1 1/2 year old twins. What are the park strollers like? Are they comfy enough for the little ones to nap? Are they easy to stroll? Are they worth the $ to rent?
