Hi Kari,
I'm not surprised that you are excited as your trip is just around the corner!
You are more than welcome to bring your own stroller from home and use it the Disney Parks. Lots of Guests prefer to do this as they feel that their children are more comfortable in their own strollers.
Strollers are available for rent at a variety of locations throughout Disney Theme Parks, Disney Water Parks and the Downtown Disney Area.
The current stroller rental fee is:-
$15.00 USD per day for a single-passenger stroller
$31.00 USD per day for a double-passenger stroller
$100 USD credit card deposit is required per strollers rented at the Downtown Disney Area. The rented stroller must be returned to the original rental location to receive a credit card deposit refund.
For Guests who require a stroller rental for multiple days, you can purchase a length of stay rental ticket where you make a one-time payment transaction for as many days of rental as you will need. Upon visiting a Disney Theme Park, all you need to do is show your receipt at the stroller rental location and you will be expedited through the queue with a reduced wait time.
The multiple day rental fee is:-
$13.00 USD per day for a single-passenger stroller
$27.00 USD per day for a double-passenger stroller
Wishing you a magical trip filled with memories which will last lifetime!
