Most of the hotels affected are located in downtown LB, which is strictly for business as there are no tourist attractions there. Very likely most will downsize and turn the excess rooms into long term rentals or apartments.
The Queen Mary Hotel will likely close as it has been a perennial money loser. Look for the Queen Mary to be headed to the scrap heap.
I’m not sure who can afford to go there on business any more. On our last trip there - and not just the last one we made, the last one we will ever make - the tax and extra charges on the car rental and hotel room were more than the base charges for the car and room. Just ridiculous.
What if they turn it into a flop-house? It isn’t a hotel, you rent it by the week as housing.
