My DD sprang something similar on us. We had it in our yard. we cleaned out the garage and used plastic rolls to cover the walls,and ordered a large tent and tables & chairs. we had it catered and served buffet of hot dishes. We had the food & bar set up in the garage. we hired a bartender& waiteress. The bartender made sure their was ice and glasses & let us know if their were any problems . We only served iced tea, beer, wine & pop. The waitress keep the food filled and cleaned up & put it all away. Their cost was well worth it as it allowed me to visit with our friends. We had family that provided the music & we talked to all our neighbors & made sure they were ok with it. We had a great time , put it together in about 5 weeks and didn't spend that much. cau
