Hi Kimberly,
Welcome to the Disney Parks Moms Panel and thank you for your question.
My son had been to Walt Disney World Resort 3 times before his second birthday, so I can guarantee that you, your boyfriend and your twin cuties are in for a magical time! First of all, any attraction that is listed as "any height" means that everyone can join in on the fun. Please consult this handy list of
Height Requirements for Attractions at Walt Disney World Resort at the Disney Parks Blog for more information about which attractions will be available for you to experience as a family.
For more fun tips, please visit the
Planning for Pre-School Kids and Little Ones page. I've found the Preschool Parent's Guide to Walt Disney World Resort to be particularly useful.
One final personal tip: my little guy loves splashing around in the water-based attractions like
Casey Jr. Splash 'N' Soak Station so be sure to bring a change of clothes for them in case they get soaked. I've found that a dry toddler is a happy toddler!
Please don't hesitate to come back and ask us any other questions you may have about your upcoming visit.
Have a Magical Day,
Lynne
