If you mean Feb 2020, that is Presidentsā Day weekend, so yes it gets quite busy. Iām not sure where you are from but school vacations are all over the map. New England public schools do tend to have a vacation around then, but not all the same week (ours is the following week). POP will probably feel more crowded that weekend, especially if those are the resorts for the gymnastics teams. Note that CBR and the Bayou section (which includes preferred rooms) at POR do not have elevators if that would be a concern (you mention an upcoming surgery). I think a Preferred Room at POP will be closer to the main building than Preferred at CBR or POR, but that might just be my perception.
Enjoy your vacation and good luck at the gymnastics competition!
