What is the difference between a quad hotel room and a quadruple hotel room?
The only thing you know for each is 4 people in the room. Two Queen beds or 4 single twin beds or a Queen and two twins would all be 4 people. One could be larger than the other. Normally there is a hotel web site with photos. Or, telephone if possible. Quad is just a short form for quadruple. There is also little known when it says Premier or Deluxe or Luxury without looking at each.
