Just an aside: last year we went on a 14 night cruise. Our room attendant surprised us the first night by leaving an 'animal towel' on my wife's bed. We enjoyed. Second night: another animal. Third night: another.
The problem was, we didn't know what the Etiquette was. Some of these animals were so ornate, requiring three separate towels (or more!) that we looked upon them as Art, and so hesitated to disband the fluffy animals. Yet, we needed towels. However, we did not wish to offend the room attendant.
By the tenth night it was becoming oppressive. The animal towels were reaching heights of artistic lunancy, obviously requiring hours of tedious twisting, pulling, stuffing, etc. We began to dread entering our room at night, wondering what hideous white-towel creature was awaiting us. On the 12th night it was a life-sized orangatang (I am not kidding; well, somewhat). I believe it used up every towel on our deck. We tried to dismantle it, but to no avail. The dozens of towels were too cunningly intertwined. We shared a bed that night, due to the orangatang having my wife's.
We left the orangatang intact, and our room attendant gave us respite for the last two nights of what should have been the cruise of a lifetime.
Since we were repeatedly told that 'tipping was not required', we knew that we had to pay this person for making it impossible for us to bathe for a fortnight.
I hope the foregoing explains, in some small way, my opposition to towel animals.
