Hi Margaret!
Welcome to the Disney Parks Moms Panel. I am so happy to help you
plan your Walt Disney World Resort vacation with your little ones. We brought our boys when they were just about that same ages and we created so many magical family memories. You are correct that you will not need theme park tickets for your kids as Guests under 3 years old receive complimentary admission. Also, Guests under 3 years old do not get meal credits as part of a dining plan. When my boys were that age, I shared food off of my plate since the dining plans come with so much food!
All Guests listed on your Disney Resort hotel reservation will receive
MagicBands, even the littlest Mouseketeers. So, both of your little ones will get MagicBands of their own, which can be sized for smaller wrists by removing their outside grey border. From my experience with my little ones, MagicBands can be sized to be incredibly small and should fit your little ones with no problem!
Be sure to consider adding
Memory Maker to your vacation to capture all of the memories you make. T-T-F-N, ta ta for now!
