Hi Robin!
My family had a chance to stay at
Disney's Coronado Springs Resort once and we absolutely loved it! The Southwestern-style theming, 22-acre Lago Dorado and gorgeous landscaping make it a beautiful vacation escape. I also think the City of Cibola pool area, complete with Mayan pyramid and 123-foot water slide, is one of the best swimming areas on Disney property.
The Junior Suites offer either 1 King and 1 Queen-Size Sleeper Sofa (sleeps up to 4) or 2 Queen and 1 Queen-Size Sleeper Sofa (sleeps up to 6), plus 2 bathrooms. The space is about the size of two standard rooms put together. Based on the information I can find, it looks like most of the Junior Suites are located in the Casitas section (1 and 3), with 2 Junior Suites located in the Cabana section (8B and 9B).
I hope that helps with your planning, Robin, but please let us know if you have any other questions. Have a magical vacation!
Beth
