Millybess:
I didn't get the rum either, but when I asked about it at custonmer services they said I'd get a bottle on leaving. Well the next day there was a bottle of red wine in my room, so I assumed that they had given me that in lieu of the rum.
I was quite happy with that so I never went back to ask for the rum. I agree with you (hooray) about Night Porters though, they never seem to be the friendliest of people.
