Even though I'm not a "bigger" traveler, I listened and enjoyed the episode. They handled the topic well and made a lot of good points and suggestions.
I actually wonder if part of the reason so many hotels have moved away from tub/showers to just shower stalls has anything to do with there being more bigger people as well as more older people who may have difficulty getting in and out of the tubs. I certainly understand why Kevin and others prefer the shower stalls though personally I'd much rather have a tub, which is probably also true of families with smaller children who take baths, not showers.
