Where price discipline lives in this map
Price discipline is not "we never discount." Price discipline is "we discount the right channel, in the right segment, at the right lead time, by the right amount, and we can explain why to anyone who asks." Most hotels confuse the first sentence with the second.
Three places discipline lives
First: the rate calendar. A disciplined hotel has a published BAR for the next 365 days that is reviewed weekly. Changes happen in increments of €5-€10, not €30 jumps. The calendar is visible to the front office, e-commerce, and reservations. Anyone who needs to quote a rate has the same answer.
Second: the rate plan structure. A disciplined hotel has 4-7 rate plans — BAR, BAR-LOS, advance purchase, member rate, corporate, group, wholesale. Not 32. Every rate plan has a documented rationale ("BAR-LOS triggers at 3+ nights to convert leisure stays"; "member rate is 7% off BAR for direct loyalty"). If you cannot defend the rationale, you cannot defend the rate.
Third: the channel hierarchy. The direct channel always sees the best rate. The OTA member rates may match direct. The OTA public rate is never below direct (unless you are intentionally running a counter-parity experiment for 14 days with the GM's sign-off). The wholesale rate is the net-of-commission rate and is never visible to a guest browsing the OTA.
Where discipline breaks
Each of these breaks is small. None of them shows up in your RMS dashboard. All of them compound across a quarter. The discipline is in the operating routine — the weekly parity audit, the daily rate-plan review, the SOP that says "no one outside revenue touches the extranet."
