You could almost travel with only one bottle because stores and people are closer together. It's easy to get water. Big weight saved.
sleeping bag is one thing (I would personally always want a light summer one myself) but one water bottle?? Thats a big no-no for me, not having enough water when it is hot makes me feel pretty crappy pretty quickly, I would be very wary of going the one water bottle route, as would most of us I suspect.
