Thanksgiving Storytellers cancellation

[kikismom]

I am super stressed out. I have a reservation for five people at 12:40 and a reservation for four people at 3:30 Thanksgiving at storytellers. We have five people. Normally. I know it's not an issue just to add somebody at these restaurants, but it being Thanksgiving I don't think it's going to work. Our flight gets in at 10:20. If there are any delays, we are going to miss our our 12:40 reservation. I need to cancel one of them very very soon. Which one would you cancel? Does the modification work for the 72-hour rule for these special meals? I just don't want to be charged the full price for five people on a cancellation.
