Hi Jill, and welcome to planDisney!
The idea of spending time with your family while at
Walt Disney World Resort is priceless! I can only imagine the smiles that will be on your faces when you experience all it has to offer.
Yes, you can add a theme park ticket for the dates in question, as long as theme park availability exists. I recommend checking the
Theme Park Reservation Availability calendar to ensure that you can add your son’s para to the theme park reservation. If there is no availability, you will not be able to add the theme park reservations at the theme parks you desire. You can still visit your selected theme parks if you have the park hopper option added to your theme park tickets. As long as it is not at capacity, you can visit the theme park of your choice after 2:00 PM, after visiting the original reserved theme park for that day.
Please let us know if you have additional questions; we are here to help.
Have a magical time!
