I love sea days, as well. You can either relax on your own schedule, or participate in some of the many activities that will be scheduled for that day. You will receive a daily program, called Carnival Capers, while onboard that will list all the activities and the times they are held. There's something for everyone on a sea day...enjoy!
Ahhh, so you want that blood pressure lowering booze! Well, you start early and finish late and any booze will do! But seriously, the most days at sea we ever had was on a Grand Princess cruise where we did not leave the ship for 9 straight days! It was heaven on earth and by the 5th day we were all comatose. Probably added 10 years onto our lives.
The GREAT thing about sea days is you can do as much or as little as you want. You can kick back and relax or try to do everything that is planned for on board activities. I love the wine tasting, sitting on my balcony watching the magnificent ocean, going up on the lido deck and having a few libations while listening to the band, sitting in the hot tub, loosing a little in the casino, taking a drink back to the room for a nap, getting up to have a drink before dinner, and of course, having a little to eat along with a few drinks. On our up-coming cruise, we have 2 sea days on the way out and 2 on the way back. I'm so ready to go! Best wishes and have a wonderful cruise!
Sea days are when they offer the extra activities, vegetable carving demos, towel animal demos, galley tours, wine tasting, champagne art auctions, etc. Or just pretend you are at the resort and lounge by the pool. Walk the promenade deck if you feel energetic and visit with everyone else doing the same. You will only have nothing to do if you want to do nothing.
I would also suggest to make reservations as quickly as possible for the various activities, free or not that you may be interested in, like the Spa, a wine tasting or a gym class.
If you like to sleep in on those days, then make sure (if it's not too late) that your cabin is a quiet one (let's say not next to the anchor at the front of the ship or next to a busy elevator).
Now, on port days, if you stay on the ship then this is when you can really have a good, quiet time pretty much anywhere you go on the ship. Look for a Southern Caribbean itinerary for that though where you're in a different port pretty much everyday and don't mind skipping going ashore once or twice.
there lots to do , i like the days at sea the best. even better then getting off the boat! i think as it as a floating hotel.
pools, drinks, shows, shops, and eating are manys things to do. you will never find a dull minute on board.
