As for the Cloud City windows: my compromise is this: keep most SE windows in the quite, calm scenes where Lando is giving a tour of the city.
And instead take out more windows in the quicker paced chase scenes. It will be a good contrast.
The clastrophic feeling is not needed in the earlier Lando scenes, because they are not supposed to be threathening. But it definately adds to the escape sequence.
It's the best of two worlds, IMO.
