Some people like that non casino environment to their hotel but if that is the case then why go to Vegas for?
If the resort has a casino, I rather do them because I like to walk downstairs just to fetch me a drink and I like to walk around where there are action, lights and things to be seen. If I want some peace and quiet, I can always book a hotel stay anywhere else in the states.
I stayed at nearby INN in vegas before. That is only because I was a starving student and still wanted to see the limelight. Go to vegas enough and you'll learn a thing or two.
