Frequently Asked Questions (FAQs) About Hotel Terminology

Q: What is the difference between ADR and RevPAR?

A: ADR (Average Daily Rate) only calculates the average price of the rooms that were actually sold. RevPAR (Revenue Per Available Room) factors in your unsold rooms, giving you a more accurate picture of your overall financial performance and occupancy efficiency.

Q: What does PMS stand for in modern hospitality?

A: PMS stands for Property Management System. It is the central software that hotel managers use to handle reservations, check-ins, check-outs, room assignments, and billing. In 2026, a modern PMS also integrates with AI tools and channel managers.

Q: Why is Rate Parity important for hotels?

A: Rate Parity is the practice of maintaining consistent public rates across all distribution channels (your website, OTAs, etc.). It ensures guests trust your pricing and prevents OTAs from undercutting your direct booking efforts.

Q: What does it mean when a hotel is overbooked?

A: Overbooking is a strategic revenue management tactic where a hotel accepts more reservations than it has physical rooms. Management teams use forecasting models to predict “no-shows” and cancellations, aiming to hit exactly 100% occupancy without having to “walk” (relocate) a guest.
