We went on our first cruise in April, and we gave everyone 30% more, except our head server, Erik, who was rather arrogant and not a pleasure to be around. We gave him just the recommended amount. We also gave a phone card to each person, and I'm so glad I had read the recommendation on this board to do so. Our cabin host thanked me profusely for the phone card - he was celebrating his 5th wedding anniv the day we were to arrive back in Port Canaveral, and was planning to use the card to call his wife in Jamaica. He was so grateful for the extra thought - it really does go a long way.
