It might be confusing if they weren't constantly referring to what planets they were headed to, or if they had three different groups on all three planets at the same time and the planet was the establishing shot used. But everyone is on Hoth, Luke is on Dagobah while Han and Leia go to Bespin, and all of the establishing shots are of Yoda's Hut or Cloud City, so I think it's safe. I feel that Ady's Dagobah is a nice shade currently, and definately better than the blue every single thing in the 2004 DVD is.
