When my husband and I plan for a cruise we automatically plan for the tips. We have never given the suggested amounts to the Dining Room waiter or Asst. Waiter. We always give more. These people really spoil you. Anyway, we just got back from a 10day Caribbean on the Horizon and left about $250.00 in tips. We just know that this is the way it is. Also, according to our waiter, NO tips are split on the Horizon. He said he can't speak for other ships, but what he gets he keeps. We wanted to make sure of that before we gave him more. I do know also that our tablemates also gave more. Anytime you order a mixed drink or anything from the bar including a coke 15% is automaically added.
