First cruise on RCL and with child

We have cruised before but not on RCL and it was before we had my daughter (she is almost 5).

We will be on Oasis of the Seas in Sept. Eastern Caribbean. What are the family must do's? What should we skip?

What should we prep for?

No need to "prep" for a vacation! Your daughter is the perfect age to enjoy the kid's club activities. Do what you want, when you want. It's not a marathon, and there are no prizes for doing more than everyone else! This is fun time...a vacation...time to relax and enjoy each other and new places! Get a guidebook on your ports from you library...the more you know, the more fun you can have "on the cheap"...which is important when you have kids and expenses! Go with a "devil may care" attitude...just have fun! VACATION! Woo Hoo!
