OK, I understand we will have servers that move with us through each dining rotation. That's for dinner though, right? What if we choose to eat in any of the restaurants for breakfast or lunch? It is my understanding that it is open seating at those times. Should we be keeping track of those servers also and include them in the tip envelopes as well?? Thanks for all that respond. I really want to get this tip thing down pat so that I am not worried about it everytime someone brings me something! I am a first time cruiser and I certainly want to do what is customary and appropriate. Thanks!
