I mean, the electric scooters used by disabled guests could be considered a hazard or nuisance to those around them? Should Disney ban those?
I guess I don't believe that strollers are a hazard- how many stroller related injuries have there been at the DLR?
Are they a public nuisance? Or an amenity that helps ease the day for families who bring their young children (let's remember- Disney's not just for adults). If a single mom takes two toddlers, is it unfair for her to bring a larger, double seat stroller?
As far as the ugly aspect goes- the simple act of having people inside the park uglifies it. The most beautiful photos are most often the ones where the park is empty, or close to it.
Maybe I just go on the wrong days, but stroller parking has never gotten in the way of where I want to go. Disneyland is a small, cramped park- choke points exist but they're not caused by strollers. They're caused by poor planning when building the park and the thousands of guests that visit each day.
Disneyland is a vacation destination that tries to get families to stay for days at a time. The last thing they'll do is limit the strollers- something that makes a day at the park with young children loads easier- and miss out on potential visits. If the park was at capacity daily, they'd maybe consider it, but until then, don't expect anything to change.
How many "huge RV sized strollers" get brought into the park vs normal sized ones anyway? Would turning them away actually alleviate any crowding, or would it cause families to just bring two regular sized ones?
