I want good coffee, and I want it BEFORE I get dressed. Maxine brought a small coffeemaker in October 09 and we never had a problem. On the January cruise, I did the same, but we got a message on our phone saying that we were not allowed to use it due to fire safety, etc. So, I wound the cord around it every time I finished with it. Until then, the privacy please card was kept in the door. No more problems.
They don't line the trash cans in the room, so I brought zip plastic sandwich bags to dispose of the grounds. After the call, I grabbed a handful of those white bags from the public restrooms that they use for feminine product disposal, and put the zip bag in there so they wouldn't give me crap. You KNOW the steward isn't going to check that for contents!

Wendy picked up the coffee maker for me in Ft Lauderdale at the Walgreens store for $10, and it came with a reuseable filter basket.
