Not necessarily. At least for me, it's always a choice of two things, location plus eco settings in the hotels. It doesn't take much to be eco: urban eco hotels can spare more in carbon footprint from their guests walking by being nearby to the center, than saving up on dry cleaning but being too far away from the places one usually goes to visit once in a vacation.

I think that a lot of hotels in urban settings are starting to become more eco, through retrofitting practices and things like the LEED certification program, which still makes these hotels a better choice over a non-eco hotel in an urban environment.
