9: Go Easy on the Alcohol. Yes, I've drunk my fill of mango mojitos and sung Billy Joel songs at piano bars until the wee hours of the morning -- and I've loved every minute of it. But if you're looking to stay healthy onboard, excessive drinking is not the way to do it. Try to avoid boozing it up until you're sick or so drunk that you can't get back to your cabin.
A hangover is the least of your worries -- excessive drinking can put you at risk of getting into a fight, becoming sexually compromised or even falling overboard. If you do plan to party, designate one of your travel companions as the sober one who can watch over the group and keep everyone safe.
10: Tell the Truth. Our last tip is more about keeping everyone else healthy. Many cruise-ship illnesses come onboard on embarkation day with each new crop of passengers. These days, most lines ask guests to fill out forms indicating whether they've experienced certain symptoms in the past week. If you've been feeling under the weather, please answer these questions honestly. You will then meet with someone from the ship's medical team to determine the best course of action.
It does not mean that you are automatically kicked off the cruise. While contagious cruisers may find themselves quarantined in their cabin for the first day, you are doing a great service to the rest of the passengers and crew by not spreading your virus around the ship and causing more travelers to become ill.
