Re: Multiple Hoses...
Multi hose hookahs are where its at for me. Granted you will have trouble if 3 people are all pulling at the same time, but that's just common sense. Even most multihose hookahs don't seem to be designed to have 3+ people pulling at once. The novelty is that you don't have to deal with passing, and waiting for the hose to go around the circle and back to you. When you arent passing around a hose you also have less chance of accidently knocking over your hookah.
If you go multihose I would recommend an Auto-Seal system. If not(at least with my friends) you'll be reminding them to plug their hose every 2 minutes.
