Welcome! Sounds like the only thing you are missing is pirate costumes!
We've only sailed once before, on the Magic. But we did learn a few good tips.
*Eat lunch in Parrot Cay, the first day (and others if you want the buffet). They serve the same lunch buffet but you are seated at a table and a server gets your drinks and keeps them filled. More relaxing than the regular buffet, in our opinion. Quieter too.
*Directly after the lifeboat drill, get up to deck 10 to find a spot to watch the Sail Away Party from above. Generally less crowded and you get a good view of everything. But, you need to get there early to get a spot by the railing. We are going to bring our cameras to the lifeboat drill this time
*Bring your own booze in your carryon. It is allowed by
DCL, as long as you carry it on. This way, you get what you like and it is much cheaper.
*Check the navigator bar hours for 2 for 1 deals. They are sometimes listed in one of the bars just before dinner service.
*The Disney shows are not to be missed and children CAN sleep through really loud music and pyro techniques, if you are willing to hold them while they sleep. DD fell asleep halfway through every night, she was zonked, so we didn't have to miss any of the shows. Her normal bedtime was around the same time as the shows.
