The lounge still exists - as a new build hotel opened under 2 years ago, it's a specifically designed space with outdoor terrace, not somewhere made of a few bedrooms joined together like in some other hotels.
It's just been closed since the start of Covid. I fully expect it to re-open.
As regards their books - they have been hosting a lot of offshore / ship workers / quarantine passengers, so I think not as bad as it could have been (e.g. Treetops, DoubleTree and Garden Inn are all closed now).
The two Hamptons in Aberdeen (Dyce / Westhill) have been used for offshore workers prior to helicopter flights offshore and have not been bookable by the public.
