I've probably used up my quota of silly questions, but here it goes!....
Looking through past postings that I searched on the site, it looks like the difference between a room with a double and one with twins is this...
Double-Has one bed that is the size of a US double, which is smaller than a US queen size bed, but comparable to US doubles.
Twin-Room has two twins that are pushed together. Comparable in size to king size beds. Are they always pushed together?
Looking for rooms for my wife and I and would like to get as big of beds as possible. Leaning towards rooms with twins, but remember a trip to Mazatlan a few years back with friends where the double beds were attached to the floor by raised tile stands, which made for some interesting sleeping accommodations!
