I have up to 15 people usually smoking form 1 Mya Acrylic at my house, so i have 4 hose ports and 4 Nammor hoses.
Honestly, passing 1 hose inbetween 15 people isn't gonna fly. And 2 hookahs is too much money and too much trouble.
I have posted about this before, and everyone here loves 1 hosed hookahs.
I have to say this....YOU DON'T GET LESS SMOKE!
Really, you dont', actually that doesn't even make any sense at all. Maybe i should start taking cloud pictures to prove it.
