Since we can't stay with people we don't know, we have to stay at hotels. Hotels, in one form or another, have been around as long as strangers have. They are a main staple of society. However, some hotels can be downright wasteful. They may air condition rooms when there is nobody in there. They may do all sorts of eco-unfriendly things. Then again, they might be a solar-powered paradise. We don't know. We have to ask.
I found a list of things to ask a hotel via the Independent Traveler.
1. Is the hotel locally owned and operated? If not, is it at least staffed by local employees?
2. What kind of recycling programs does the hotel have (aluminum, plastic, paper, gray water, composting)?
