These are some cruise tips I collected from reviews for months prior to our trip.......

On the ship:
1.Play bingo at the end of the trip-the jackpot is $14,000 and a free cruise
2.book spa/salon appointments as soon as you get on board
3.wait until last day to buy t-shirts and sweatshirts-they go on sale
4.See ice skating show. If you want to skate, you have to wear long pants.
5.go to karaoke
6.parades at 11:15 pm (don't miss)
7.DON'T BE LATE BACK TO THE SHIP
8.take underwater cameras
9.arrive at the shows a little early for better seating-balcony is the best
10.take an outlet adapter to add more outlets. The room only has one outlet and none in the bathroom.
11.take a combo iron/steamer. There isn't an iron in your room.
12.The Windjammer is a good place to go for breakfast.
13.Eat dinner every night in the dining room. Best Place.
14.take an alarm clock
15.take a garbage bag for dirty clothes
16.put colored ribbon on all of your suitcases to make them easier to be spotted.
17.Take your own beach towels. If you use RCCL's and don't return them they charge your room $10 a piece.

In Jamaica:
Do Dunn's River Falls-no excursion
On pier-go outside of gate to the taxi's along the street-taxi full for $5
Do not pay for round trip taxi
Go to Fern Gully
If you have time, see St. Ann's Bay
Shopping stops: Soni's Plaza and Taj Mahal

In Labadee:
if you want to get hair braided, do it here.
If you want to rent waverunners, do it here. Book it through an excursion in advance over the internet. Usually booked by the time you get on the Voyager.
Don't purchase anything to eat. RCCL provides a nice free meal.
Take a few extra dollar bills for tips
BARGAIN at the market
Make sure you go and see Dragon's Breath at Dragon's Point
Bring water shoes.

In Cayman Islands:
If you want to do an excursion, snorkel/stingray combo
Go to Rum Cake Factory
Go to Sting Ray City
If you have extra time, hang out on Seven Mile Beach
Visit a place called "Hell"

In Cozumel:
If you want to do an excursion, do Catamaran Fury
Go to Carlos and Charlie's
Go to Chankanaab Lagoon.

I hope these help.......
