Hi Laura,
Thank you so much for visiting the Disney Parks Moms Panel with your question. I believe that you have a Disney Vacation Club deluxe studio reserved for your stay at
Disney's Polynesian Villas & Bungalows. My family and I recently stayed in one of these, and it was a lovely place to stay. The tropical theme is relaxing, and the proximity to Magic Kingdom is wonderful! The fold-down bed in the deluxe studio is adorable, with a rendering of a slumbering Lilo and Stitch on the backdrop.
I spoke with a cast member today who let me know that there are in fact bed rails and pack 'n' plays available at this resort. You might find a pack 'n' play in your studio when you arrive. If you do not, you will need to request one, but one should be available. There should also be bed rails available at the resort, but you will need to request them. They will be brought to your deluxe studio once you have arrived. Finally, there are some full-sized cribs available at this resort; however, they are limited. If you are interested in a full-sized crib, I suggest that you note this request on your reservation. Please do know that this is a request and not a guarantee.
I hope that this information is helpful for you, Laura. Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions.
