If you enjoy drinking. On the first day bring some dollar bills with you and give cash tips to a couple waiters and a couple bartenders. You will find that these people will seek you out during the week. Also ask your stateroom attendant for robes. Normally only for guests with at least 5 cruises or more. But its how you ask for things that can get you the perks.
Don't miss the QUEST....
Its an adult scavenger hunt. I can not say anymore about it or someone will kill me. But make sure you attend and participate. Arrive early so you can get front row seats in Studio B.
Make sure you go to the Ice Show.
If you want to LYAO make sure you go to the Belly Flop Contest and the Mens Sexy Legs Contest. Make sure you have film in your camera.
The slot tournaments are fun as are the Blackjack Tournaments.
Everynight you will receive the next days Cruise Compass which is the daily planner. Look at it before you go to sleep so you know what is happening at what time.
If you like to shop go to the Prt shopping talk in Studio B. They sell a shopping book for $20. With the book you can get a Del Sol bag for $5 which is a tote bag that changes colors. Its worth getting the bag. And in turn you can pick up jewelry for your nieces just for visiting certain stores. They are trinkets but fun for the youngsters.
Have a wonderful time.
