Truly, it is a fantastic trip for my first family cruise vacation. We are family of 4 from Toronto, Ontario, Canada.
Navigator of the Seas by Royal Caribbean: The ship was loaded with every activity for every age group. It is so calm and stable on the sea. My daughter (11 age) loves the Adventure activities. My son (16 age) loves the Teen activities. We love every activity (show, game, food, dinner & room service etc). Except one thing is the smoking area is not enclosed. We have to smoke the 2nd hand as we pass the Bar on deck 3 & 4. Also on the deck 11 near the pool, all the smokers are gathered there.
Labadee (Royal's own port): Not much to see but just relax on the beach. Be sure to negotiate the price from the local reseller.
