I want to take 15 or so people on a large boat cruise around a huge lake. It's a very popular lake and it's huge. Do you think this is a good idea? The boat renter let's you bring your own drinks and food. There is a grill on the pontoon. Do you think it would be rude to ask people to bring a side dish for a potluck, if I bring the meat to grill and buns. What about drinks? I probably should supply the beer, wine, water, etc. Any thoughts? Any thoughts on decorations or games on a pontoon?
