Hey Howdy Hey Melissa and welcome to planDisney!
I bet you all are super excited about your upcoming trip to the Most Magical Place on Earth just days away! There is so much to look forward to for your upcoming vacation but it sounds like we may have an issue with crowd levels. I will be happy to give you more information on these as well as some planning tips to consider to help manage crowds. Giddy up!
As you know Melissa, crowd levels in Disney do ebb and flow to a degree and it is things like RunDisney events and cheer competitions that Disney offers to keep the levels and interest high in the parks. One super useful planning tip would be to use a crowd calendar. If you search for "Crowd Calendar for Disney World" you will find several options available. These are super useful as they will use the current calendar of events for the resort as well as historical data to give you an expectation of crowd levels. Some even go as far as recommending which parks to visit on which days per the predicted levels. I will say from experience being down with these cheer competitions, crowd levels don't fluctuate terribly so you may still enjoy an experience with lower crowd levels compared to other times such as spring break and the summer vacation season when crowds are much higher.
While crowds in Disney are inevitable despite the timing, there are ways to manage them. If your son has difficulty waiting in lines, I would recommend you look into the
Disney Disability Access Service (DAS). This is a super helpful option for those with medical conditions who want to experience the Magic of the resort but have difficulty in crowds. You can request a virtual interview with a Cast Member and then as long as you are approved, you will have the ability to access DAS Advanced Planning to select 2 attractions to experience before you arrive in the parks with a rolling 1 during your visit. This may be super helpful for you during your visit to make the most of your Magical vacation.
I hope this information helped you get a better idea of what to expect on your upcoming vacation. Please feel free to reach back out and let us know if you have any further questions, we are always happy to help!
Have a Magical day,
Nick
