Welcome aboard, Tamara!
The countdown is on and you've got excitement in the air in your household already. How awesome to be looking forward to a magical voyage in just a few short couple of months.
When you go through your online check-in, the system will require credit card information for your anticipated charges throughout your voyage. For Port Adventures, you should definitely plan ahead as much as possible, since a lot of the adventures have limited spots and they do fill up pretty quickly. The charges for each port adventure will not be charged to your credit card until after you embark. You do have 3 days prior to the port adventure schedule, to make changes or cancel your earlier chosen port adventure.
I am assuming you are inquiring about Nassau in the Bahamas. One of the more popular family port adventures is the
Atlantis Beach Day & Discover Atlantis listing. It's a mellow adventure for the whole family and allows you to enjoy some beach time fun and a quick tour of Nassau. You've also got lunch included in the port adventure and the whole day to spend at the Atlantis Beach resort.
I hope this helps. Let us know if you need any additional information.
Happy planning, Tamara!
