Hello, How much money do you have to work with? You could have it outside depending on time of year and all that good stuff and have music there that is fun to hang out too and dance too. THe dance floor could be in the grass or you could make a dance floor using wood as the floor and outline the floor with those standing candles that keep bugs away and you could also add lights above the dance floor in like a square to add a nice touch. you should come up with a theme and go from there. Hawaiian would be one, then you get decorations that match that and have food that also goes a long with it. You could have pina colodas, strawberry daq. without alch., your invitations could be hawaiian as well and you could tell everyone to dress hawaiian to add to the party. Hope that helped you out some. If you need more help, let me know, Jessica
