Thanks for writing again, Laura!
The quick answer is YES, there are a few rooms at All Star Music that have King size beds (approximately 4 per floor, per building).
Doug answered a similar question last year, and since he did such a great job in his response, I'll provide
THIS LINK so you can read more details for yourself.
I especially think that Doug's suggestion to call the resort directly just before you arrive is critical, if you want to make sure your request is noted in your reservation. In my experience, it works best to call only a few days in advance (3-5 days, probably not 10) as the resorts don't always have access to your records until just a few days before you arrive.
By the way the direct number for All Star Music is (407) 939-6000. This number is NOT for reservations -- it's just for specific questions like checking on your reservation request before you arrive.
Hope that helps!
