We have 182 people on our invite list plus 17 more on tier 2 that we'd like to invite if we have space.
My venue can accommodate 184 people for a plated meal, but only 152 for a buffet. We would prefer a buffet, but I'm worried that we won't get enough "no"s to be able to invite everyone we want there. Is it incredibly tacky to ask for meal choice on the RSVP as if there will be a plated meal, and then if we get enough "no"s switch it to a buffet? Or, is there any non-committal language we can use on the RSVP card that isn't tacky? Something like "Depending on the number of guests, we may be serving a plated dinner or a buffet, but we would appreciate if you let us know which meal option you would prefer."
