Hi Therese,
Thank you so much for visiting the Disney Parks Moms Panel with your question. A stay at
The Villas at Disney's Grand Floridian Resort & Spa sounds lovely. I love the elegant yet welcoming feel at this resort. With a two-bedroom villa, you will have plenty of space for your party, including the twins!
Generally,
Disney resorts provide Pack 'n Play cribs. These are play yard-type cribs. Generally you should find one in your villa, so it was a good idea to request a second one for the second twin! There are a limited number of more full-size cribs available at some Disney resorts. I recently saw one of these being delivered at Disney's Polynesian Villas & Bungalows; however, I think that that these cribs are more rare at the Disney resorts.
When you head into the theme parks with the little ones, do be sure to take advantage of the
Baby Care Centers. Located in each of the Walt Disney World theme parks, these centers are a great place to feed and change little ones in an air conditioned break from the theme park.
I hope that these thoughts are helpful for you, Therese! Please do let us know if you have any further questions.
