Our wedding is small, in a semi private dining room of the hotel where we're having the ceremony. I didn't want to crowd up the area with a seating chart sign (since I'm having a welcome sign), but I plan on having marble coasters with the guest name at their place setting (to double as favors). Do you think it's okay to not have a sign letting them know what table they're at but just have them find their coaster? We have 35 guests, with 5 tables.
