Yes, review the ship map available on DisneyCruise.com. Just got off the ship on Monday, for our second Dream cruise but memorized where everything was before hand. The ship is a lot bigger and you want to see every part. I was able to use different elevators and stairwells after such things as movies, shows and dinners. That will also get you and the kids more excited about the trip.
Ask each other questions such as:
What is the restaraunt on the 2nd floor?
Can you get to the Movie Theater from deck 3?
Is the drink station on deck 11?
Ensure you get the 1100-1130 time to arrive at port. Where your bathing suites under your cloths so you can ride the Aquaduck before the boat gets full.
