My wedding is in 10 days!! I already had my final guest count and paid for the catering. I recently had a guest who told me they couldn't make it weeks ago to just message me saying their plans fell through and asking if they can still come. I already have my seating chart and everything done. How to I tell them no without sounding so harsh. I am such a push over and I feel bad but it's 10 days before my wedding. I don't have time to scramble and find 2 more spots and contact the caterer. Help!!
