We are doing a welcome party from 8-10pm the night before the wedding at the hotel where our block is. We are doing a small beer/wine bar for those 2 hours as well as serving a large specialty grooms cake, fruit/dip, cheese/crackers. It is not a dinner and not advertised as such. We are hosting a rehearsal dinner much earlier in the late afternoon/early evening during dinner hours (5-7). Only ceremony folks involved are invited to the RD...about 30 people TOTAl. The welcome party was our answer to doing something for the OOT who traveled in but don't need to schlep to the RD or rehearsal itself. There's a total of 70 OOT. I set the headcount at 40 for the welcome party but if there's an adjustment, I need to let them know 3 days prior. I have already paid for 40. I am thinking of adding more $ to the bar fee (it's a consumption bar) but the food is priced per head. Being that it's not a plated dinner or a plated anything and about half of our party will already have eaten dinner...
