I purchased a pop-up tent with no flooring and it works great! I used black flat sheets on the bottom. Be sure to wash your sheets regularly...
When I do tanning parties, I let the customer lead the way on where to set up. The majority of the parties I have done, the girls don't care if they see each other. I have done a couple where the girls are more modest and set up in the kitchen, then called each on in as the previous tanner made it to the bathroom.
