Buy a few medium or large tents- put a shade structure over them- Dress them out like guest cottages in a layout that creates a living room eating area outside between them and the rv.
Get some decorative holiday lites or rope lites run them off the RV genny plug- get some rugs and some inflateable furniture- perhaps a shit load of cushions and go to one of the burner web sites that has the simply bed couch designs a friend named Sunshine invented for cheap easy luxury bed/seating lounging
Its made from two pieces of Ply wood and cushions..very sturdy easy to pack you can burn if you want after the burn. It gets hot enough to sleep outside at nite- many prefer it- But create cottages for your privacy and a community lounge- everybody should contribute some effects to make it special and unique and creative- Use the outside as much as possible it gets you out and you have more fun anyway- have everyone put there names in a box and draw out random mates who will sleep in the rv and who will use the campjurious tents that should have comfy bedding and lites a table - fans to move the air and a shade structure over them to keep them comfortable
You miss alot being privatized in a RV.
good luck and have fun.
