Hi there, Leigh Ann! Welcome back to the Disney Parks Moms Panel! Thanks so much for taking the time to reach back out and allowing us to help you plan your vacation to Walt Disney World Resort!
I know it can be quite stressful planning your vacation to Walt Disney World Resort and considering uncontrollable variables! As someone that has to consider chronic fatigue and illness, I often have to make last-minute shifts to my own plans. Fortunately, this tends to be a fairly easy and pain-free process when visiting Walt Disney World Resort!
In the past, I have made
advanced dining reservations that I have been unable to attend due to my illness. However, I was more than happy to let the rest of the family enjoy their meal while I took the opportunity to rest! In my own experience, I have never had a problem decreasing the number of participants in my party. Generally, dining locations set aside specifically sized tables based on the number of people in your party so decreasing your count by one it not too much of a problem. That being said, it is always best practices to notify the
dining location as early as possible about any changes to your reservation although Cast Members are quite understanding of last-minute changes.
I hope this information assists you in continuing to plan for your vacation to Walt Disney World Resort!
