I have never yet paid as much as £80 for a night at a Hilton property in Glasgow.

My thoughts - not especially well thought through but mostly based on reading here and planning or booking my own travel:

If I just believed what I read in the media then I would anticipate paying a lot MORE than pre-Covid for a night’s stay at a hotel in the UK. This results from a combination of the media’s myopic and extremely tedious London-focus, a big uptick in price at higher-end (ie not mid-range, business traveler type) properties dotted around the country, and general talk of “inflation”.

In practice I believe the price point now may be LESS than pre-Covid at Hiltons in some big cities that aren’t primarily tourist markets and which previously relied on solid volumes of midweek corporate bookings. This is accentuated where supply of hotel rooms at mid-price is particularly high. Glasgow fits this category to a dime, as does Newcastle. There just isn’t enough leisure business to fill the available rooms. Hilton alone has several properties (albeit different brands) competing against each other for what leisure business there is in each city.

If it’s something like this then it’s exactly like Aberdeen but without a single industry focus. Not enough leisure business for the supply of mid-range business properties.

Edited to add:
Disruption over the winter on the trains (industrial action and severe weather (such as this week where the west coast main line is closed between Carlisle and Glasgow after a landslip in the storms a few days ago)) is likely having a much bigger impact outside London.
