Ahoy, Yaritza!
You have come to the right place for advice! I'm going to share as much as I can, but please feel free to follow up with any additional questions.
You will want to complete your Online Check-In (it opens 75 days prior to departure for new cruisers). During check-in you can select a Port Arrival Time. This 30-minute window is when you'll arrive at the terminal to check-in for the cruise. Once you are checked in at the port, you'll receive a boarding number that will be called shortly after. Since you have booked a three-night cruise, I suggest a Port Arrival time in the late morning or early afternoon so you have more time to explore the ship once boarding begins (typically around 11:30 a.m.). After you complete your online check-in, you can book Port Adventures, spa treatments, adult dining, nursery hours (6 months-3 years old for a nominal hourly fee), appointments at Bibbidi Bobbidi Boutique and two character experiences for Frozen and the Princess Gathering. They will be offered a few times, and you can book both as long as they don't overlap. Don't forget to bring along your autograph books and a pen! Also, do you have a pre-cruise character call scheduled? This can be set up online and is a fun way to get the kids excited about the cruise.
Two other orders of cruise business are to register your kids for the youth programming (3-12 year olds only) and send in any special dietary requests or child amenity requests like bed rails or a high chair. This can all be found under "My Cruise Reservations."
I also want you to check out the
Disney Cruise Line Navigator app. If you have an Apple or Android device, you can use it onboard to check activities, deck plans, dinner menus and to text others with the app. It's free to download and use while aboard.
I hope I've steered you in the right direction,Yaritza!
