If you find a great deal on a Riverwalk hotel, double-check with the city when they’re doing Riverwalk maintenance. Every year, in January, they drain that open sewer to clean all the trash, shopping carts, junk and stinky mud out of it, and it will smell like a sewage treatment plant. The hotels will offer discounted rooms to suckers who don’t know any better.
