Bushkitty;Your first cruise? You'll have a great time. Serenade of the Seas; I think that is Royal Caribbean (owned by Celebrity). I prefer Celebrity, but RC is an excellent choice. Not too many hidden costs once you are on board; you will have to pay for all drinks, so go slow on those. And towards the end they will hand out what is expected for tipping the crew; that will set you back. Make sure you bring a passport. You will have to pass through both Customs and Immigration when you return.What are your ports of call?
