Hi, Rosemarie, The last time I stayed at Coronado Springs, they were in the process of updating all the guest rooms. I do not know if the renovation is complete on the entire resort, but you can certainly request to have a newly renovated room, though requests cannot be guaranteed.
The room I was in had 2 queen beds and was connecting to another room with 2 queen beds. This was a great location, so I do recommend Casitas Building 1. Make sure you request "connecting" and not "adjoining" rooms. Connecting rooms have the door between the 2 rooms, and adjoining simply means next to each other.
To add a room request to your reservation, call (407)W-DISNEY and have your confirmation number handy. List your room requests in order of preference. For more tips on getting your desired room, read this helpful information

Thanks for your question and have a magical vacation!
