I consider myself *somewhat* green, but I have to admit...those cards in hotel rooms annoy me.
YES, I want clean towels. YES, I want clean linens. NO, it doesn't matter how often I wash sheets and towels at home - I don't have to pay $199/nt. to sleep at home.
I usually launch the used towels into the bathtub or under the sink. I want clean ones!
I'm happy to recycle. I almost always pick the hybrid off the Exec Aisle if it's there. I drink lots of tap water. I always turn off lights and appliances when I leave a hotel room (although I get extremely annoyed if they have one of those systems that disables the A/C when I leave). But I still want clean towels.
