Hi Kelly,
Welcome to the Disney Parks Moms Panel! Your Walt Disney World Resort vacation is truly right around the corner. I'm so excited for you! The good news is there are bed rails available at Walt Disney World Resort Hotels including
Disney's Coronado Springs Resort. If I were you, I would call (407) 939-1936 and have them add the request to your reservation.
If you think your 3-year-old would be more comfortable in a
portable crib, you can also request a Pack 'n Play playard for your room. At that age one of my children would have been more comfortable in the bed and the other would have enjoyed the Pack 'n Play. You know your children the best so you can request what will make your time in the resort more enjoyable.
Kelly, thank you for visiting us with your question. I hope you'll let us know if we can help you with any other questions!
Wishing you a magical vacation,
Amy H.
