Unfortunately, yes, they are allowed. If yours is truly smaller than a double stroller, cool. We saw a bunch of the giant ones there in our trip a few weeks ago. I know everyone is has their own opinion, but I really hope they ban them. I have no problem with strollers and bringing things in (we do it), but those large push wagons are just way too big. Most strollers offer storage, take up far less space and are less cumbersome...with less chance for banging into people. We bring our own food into the parks, and also have a tote bag for ponchos, etc...but it all fits in a tiny umbrella stroller.
