Also, last year even though 'off the hotel strip' meant I couldn't use the $5 downtown taxi fare, when I did taxi back each night it was usually 8-10 including tip. I had Harlath lay in some basic breakfast and lunch vittles (yogurts, sandwich fixings, trail mix, bars, etc.) and then ate out w/ various groups for dinner. Overall, it was a splendid arrangement.
I lucked out (I think?) w/ a single bed in the JWMarriott, so I won't be availing myself of Harlath's chumminess - but overall last year's BnB experience was just splendid. As a fallback option, you can do a LOT worse, and probably not better.
