Lol, yes, this is fair. The hotel market doubling in revenue would be headline news at the WSJ, etc though.
We can actually get a rough sense of what's happened to the market as a whole by looking at the stock prices and cashflows of the major hotel chains. Looks like Mariott has lost a bit of value in the last year[1], same for Hilton[2]. La Quinta holdings went way down[3]. Please check the hotel chain of your choice if you feel I cherry picked these examples (Motel 6 and Best Western were my first choices, but are privately held).
Which is to say it doesn't appear that the market doubled in size.
