Hey there Oliver,
Welcome to planDisney and thanks for your question! So glad to hear you're thinking about a trip to the Happiest Place on Earth.
According to the
Park Rules and Regulations, stroller wagons are not permitted at the Disneyland Resort. It looks like the model you're referring to is a stroller wagon and is one of the
prohibited items they check for at the security entry points to the resort. Therefore, I would not recommend taking it as you would not be allowed to enter the parks with it.
However, Hakuna Mata, Oliver! If you don't have access to any other strollers, the Disneyland Resort offers
stroller rentals just east of the Disneyland Park Main Entrance! You can get single or double strollers, and I'm happy to report they work great! We rented a single stroller on our last visit and it was a really helpful option for one of our kiddos when we needed it.
I'd imagine that's not the answer you were hoping for, Oliver - sorry about that! However, I have seen families who have not been allowed to enter because they were bringing prohibited items and that is no fun, so I wanted you to be equipped with the right expectations. I hope you have a fantastic visit to the Disneyland Resort, and thank you again for your question!
Have a Magical Day,
Greg
