So if the 'plus sizers' need larger hallways, then they are going to need larger beds, larger rooms, larger toilets, larger closets, larger balconies, larger swimming pools, larger dining rooms, etc. Obviously (at least to most) it would be cost prohibitive.
How, about they come up with a 'plus-size' hotel just for those overweight and along with it they should be prepared to pay a hefty plus-size price.
