I hate it when hotels ask that you try to re-use your towels to save the environment. It is a ploy to save money for themselves. They charge a hefty fee for accomodation and then appeal to the envriomental side of everyone to save themselves money. If hotels are so commited to saving the environment they should offer credits/refunds for guests who re-use towels. Then the enviromment will be saved and guests won't feel cheated.
