The Green Miles is in Miami this weekend for the National Wildlife Federation-sponsored Carbon-Neutral Sailfish Tournament. I'm staying at the Royal Palm South Beach. It's a decent hotel, but if it wasn't right on the beach it would be nothing to write home about.
One thing that makes the Royal Palm so ordinary - its lack of green features. They give you a newspaper every day whether you want it or not, but there's no recycling anywhere - it's not even accepted at the front desk. About the only positive I noticed was the compact fluorescent light bulbs.
One little thing I do when I'm staying by myself is to leave the "do not disturb" sign on the doorknob, letting the cleaning staff know that the room doesn't need service. Do I really need new soaps, shampoo, towels, sheets, etc. every single day? I'm fairly confident they can survive more than one use.
Keep an eye on the the Florida Department of Environmental Protection's Green Lodging Program. While relatively few hotels have been approved so far, there's a long list of applicants. Once the list expands and there are more choices, it should be a lot easier to find a green hotel.
