I think I'm slightly more bothered by "...and __ additional number of guests" because you don't need the 'number of' words in there...
Agree with most hideous thing from a thrift store as a gift. Maybe do that annoying packaging thing where you keep boxing it in bigger and bigger boxes so it looks like a large gift but they have to keep opening and opening. With wrapping paper between each box.
I'd just like to say I am thankful for Wedding Wire. I'm ashamed to admit that I wanted a HoneyFund in the beginning but then you ladies helped me see the light!
