I need help providing internet access to a small camp ground

I have a friend that owns a small camp ground, and he wants to offer internet service to his seasonal campers. The closest phone to the location is about 150 ft. away to a central point in the camp ground. I was thinking of getting DSL at that location then running hard lines to several points and running wireless routers at those points. If anyone has a better suggestion, please help me.
