It would be difficult to tell if your competition has raised their prices or not, because the price shown would be more or less equivalent in either fee structure.
I’ve been on single fee for years, and prefer it. It’s the same way all other platforms work, and it makes it easier to maintain consistent pricing across platforms.
Also, I build all my costs into the nightly rate, so I don’t charge extras like a cleaning fee. What you see is what you get. No surprises.
