Welcome to the Disney Parks Moms Panel, Gita. Thanks for stopping by with your questions for us.
Bringing your own stroller for your 1.5 year old is a good idea so you won't have to
rent one when you arrive at the Disneyland Resort. While an inexpensive umbrella stroller can serve its purpose, I recommend a light weight compact stroller that has a small basket and canopy. A basket underneath the stroller seat can provide a place to stash diaper bag and small items. A canopy is also helpful to shield your little one's face when it is sunny and warm. Having a light weight stroller makes it easy to fold up as well.
There's a good chance your 7 year old will complain about walking. One can easily walk for miles within the parks, and you'll also have to factor in the distance from Main Gate to transportation to get back to your resort hotel as well. It's a good idea to wear comfortable shoes. I always pack moleskin and bandages in case any blisters develop from walking. Don't worry, Gita. There are plenty of places to rest and take breaks throughout the parks.
I hope this information is helpful for you. I wish you and your family a magical, unforgettable trip to the Happiest Place on Earth. Please visit us on the Panel again if you have further questions, Gita.
See you real soon,
Kiki
