I don't know ... these examples of lounges for jets and passenger trains have some appeal, but they're also designed for accommodating passengers for hours possibly stretching out to a couple days. Better models might be found in yachts, submarines, destroyers, or freighters where crew and passengers live for days to weeks. And even then, they're usually able to go out on deck and stare at blue skies and open seas, a luxury completely unavailable to passengers on a three month journey in space.
Let's not cramp these poor souls unnecessarily. We don't want to drive Picard mad before he gets to command the Enterprise
or the Borg will kill us all!
