We were on the Ocean Princess April of this year. We decided to take off the auto-tips because we wanted to hand out enevelopes personally. We went to the pursers desk to take the tips off our account and there was no problem or dirty looks. The last night we handed out our enevelopes with extra money in them for our waiters and room steward because they were all so great. We asked them how this worked they said they had to turn in all of the money even the extra, they were not allowed to keep it. I was disappointed because I thought they could keep the extra money over the specified amount. From now on we will just use the auto-tip and slip them extra if we would like to during the cruise.
