I will say one thing that's a positive about it. Unlike Disney, Universal is not just one big stroller parking lot and traffic jam.
They have always had better stroller parking areas than Disney, who not only has more population of strollers, higher attendance and retrofitted stroller spots.
This was well designed right down to Hogwarts Express, you can actually fold the strollers up and Team Members will place them themselves into their own car on the train.
Another great aspect of Universal, that I hope continues, is how they do rider Swap. You have the option to wait in the queue and switch in the room for the rest of your party and child to ride again, or you could wait outside of the attraction.
Your child not tall enough or guest who is not able to ride for whatever reason can still enjoy the queue and as much atmosphere as possible with the entire family.
At Disney, my kids can't always see the inside of the things in the queue line that the attractions that they could get a kick out of.
