Hi Jaclyn! Welcome to the Disney Parks Moms Panel!
Your vacation is SO close now! I know you and your family are ready to celebrate the
holidays at the Walt Disney World Resort. It really is a magical time to visit!
It sounds like you will be using a stroller with an infant carrier for your
little one when you are exploring the theme parks. While you will not use your car seat on the bus, you can carry it on the bus with you. I have seen a few families do this before! Your stroller has to be folded up for the
bus ride, so you will need to take the carrier out and hold onto it. Most likely, the Cast Member driving the bus won't mention it, but if it does get brought up, you can let them know that you are just bringing it along for use in the stroller in the theme parks.
Since you will have your hands full with a stroller, carrier, and a baby, don't forget about
merchandise delivery during your stay! When you purchase souvenirs, you can have the merchandise shipped to your Disney Resort hotel to pick up at the gift shop at a later time. That way, you won't have to carry them around with all of your other baby stuff!
I hope you have the BEST vacation, Jaclyn! Please let us know if you have any other questions.
