Hotels prices everywhere in the States now are off the charts insane. It's literally the most expensive place to travel now in the world I imagine. With all the inflation, strong USD, tipping expectations and bullshit "resort fees" now I wouldn't be surprised if it were the case.
15 years ago I was in Chicago I paid less than $100/night to stay at the Hyatt Regency on Wacker Drive thru a deal on Priceline. The rack rate for the same room is now $500/nt....$700 after all fees and taxes
