Cruises are awesome! I've been on three and am going on my 4th in September. It's addictive, I tell you...my family and I go every 9-12 months, and we even have a Mediterranean cruise booked for summer 2019. It never gets old. Just bring some Bonine or Dramamine in case you have the tendency to become seasick (I never have) and lots of casual hot-weather clothes. There is usually a formal night during a cruise and you wear dress clothes. There is plenty of food and drink---you can't walk 50 feet without running into a buffet or a waiter with a tray of drinks in his hands. You can enjoy live music and dancing, go to the comedy club, gamble in the casino, or just lay out by the pool and relax. There's shopping and fine dining too. It's A LOT of fun, and that doesn't even cover your shore excursions. Enjoy!!
