Be prepared to wait in a long line at the customs inspection when you get ready to board your cruise ship. The lines are usually long, but if you're prepared ahead of time it won't be too bad- just bring some good magazines and snacks. Buy all of your sunscreen, bugspray, chapstick with spf in it, toothpaste,lotion, etc in the states before you head out- if you buy them on the islands they're super expensive. Also, buy your cameras in the states too. When you first get on the ship, you should have a few hours in your room to put your things away and then you will have a Mustard Drill where everyone goes to the front of the ship with their life vests on for an emergency drill- be prepared, it usually takes a while and you can't use elevators, you have to use the stairs on the ships. If you want to buy perfume or anything like that- buy it on the cruise ship- it's dirt cheap and there's usually no tax!!! It's an awesome deal. Oh and try to avoid the free ice cream machines- lol i made the mistake of visiting those frequently when i went on a cruise a few yrs ago. There's usually unlimited food and drinks- just make sure u don't drink any water or anything with ice in it on the islands- only on the cruise ships because you might get ill from their water. There should be a captains dinner on your ship one night- they're awesome! Everyone gets dressed up, so bring a dress or something nice to wear. There are 5 course meals every night in the dinning hall usually and they're really yummy. Don't forget to stock up on all your medications and some draminie just in case you need it. Also, take a razor that is easy to use with you- it's reallly hard to shave on a cruise ship because the water makes the ship rock back and forth- the Shick Intuition is really good. You don't have to mess with shaving cream and it's easier to manage in a moving ship. Bring a light-weight sweater with you, because even though you're going on a cruise, it gets cold on the water at night. On the cruise i went on, alcoholic beverages were free at the open bars...but double check on the room service, i can't remember if that's free or not. Also, when you get to the islands- T-shirts are usually cheap. Also, many of those islands don't have set prices on their merchandise- so haggle them on the prices and talk them down. Also, when i went on my cruise i got harrassed quite often by men working the street vendors- be safe and be aware of your surrondings- keep your husband with you at all times and remember the way back to the ship! Bring a small flashlight just in case, and make sure you buy your swimsuite in the US- they're super expensive on the islands. Make sure you're able to go on the excursions you want to- some of them, like the scuba diving ones, you have to be scuba certified. Also, don't forget travelors checks or your Visa- you will need them! Good luck and have fun!
