On my last cruise (Carnival Dream) I noticed the quality of service was excellent, but the quantity of service had decreased from previous cruises.
- I never had an empty water glass in the dining room for more than 1 minute - sometimes it took as much as 5 minutes for a waiter to refill it
- It took much longer to clean our rooms than before
The cause was simple - the waiters and the room stewards were covering 3 times the territory than they used to. I gave them all an extra tip for being overworked
I had married into a Chinese family, and by a stroke of luck we were at sea for Chinese New Year. I had brought aboard a stack of "lucky envelopes" for tips and they all loved it.
