Hello Michele,
Thanks for stopping by planDisney with your question. May is right around the corner and so is your vacation! Visiting
Walt Disney World with little ones is truly a magical experience.
Although the dimensions of your stroller seem to fall within the permissible limits, it's considered a stroller wagon, so unfortunately you will not be able to bring it into the parks with you. I know this isn't the same as having your own stroller with you, but
rental strollers are available for use within the parks and at
Disney Springs. Both single and double strollers can be rented per day or for your entire stay. You just pick them up when you enter a park and drop it off when you are leaving.
During your vacation, be sure to locate the
Baby Care Centers in each park. These fully staffed locations provide a quiet, comfortable space for feeding, changing diapers, or just taking a moment to relax.
Hope this helps. Have a magical vacation!
Diane
