We leave in 2 weeks and we just found out that my BIL and SIL are going to have to cancel. All of our priority seatings are for 7 people. Is it okay to show up for these priority seatings with just 4 people? Or do I need to redo everything? Also, 3 of the seatings are in their name. Do I need to change these to our name or can I still use it if I have the number.
