Joni,
I just went to the cruise-locator.com site to see what is left on my cruise next October and here is how I found the rooms available. Like another poster, I'm not sure though if these could be all of the rooms left.
click at the stop to cruise search; then the words easiest way, which are highlighted; then I chose Worldperk Member
next choose specific cruise line: I chose Disney
I next clicked on the picture of the Disney Wonder; then clicked on check availability; clicked on how many people
Then I clicked on the dates I was looking for, then the category and it then listed 8 staterooms available in the category 10 I was looking for.
hope that helps! Marley
