Hello Kristina!
There is no place better than the Walt Disney World Resort to celebrate milestones and achievements. And, as far as vacation planning, coming to the Disney Parks Moms Panel is a great place to start. For our family, no trip is complete unless we visit one of the two amazing water parks at the Resort. With such a wide array of people and ages in your traveling party, I would recommend you obtain
Multi-day tickets with the Park Hopper and Water Park Fun & More options. This inclusive ticket option allows you to enjoy same day access to any of the four major theme parks as well as multiple visits (based on the length of your ticket) to the two water parks, DisneyQuest indoor interactive theme park, two miniature golf courses, access to the ESPN Wide World of Sports Complex, and Disney's Oak Trail Golf Course.
As you are planning, you will likely have many more questions. Please come back to the Disney Parks Moms Panel as there is nothing we love more than helping to plan magical vacations!
See ya real soon!
Anne
