Carnival, on some of their ships, is experimenting with presenting its passengers on their first day with a form asking them when they preferred their cabins to be serviced - morning, evening, or both.

What's your feeling about cabin cleaning?
* I prefer twice a day service
* I have no preference about how often a cabin is serviced
* I prefer once a day service - morning or evening

I prefer twice a day. That's part of the pampering cruise experience that I look forward to.
