What is a Room Night?
Room Night = One Room × One Night
The basic unit of hotel inventory. If a guest stays in one room for 3 nights, that's 3 room nights. If 10 guests stay 1 night each, that's also 10 room nights.
Room Night Examples
Example 1: Single Guest
Mr. Sharma books 1 room from Monday to Thursday (3 nights)
Room Nights: 3 RN
Example 2: Multiple Rooms
A company books 5 rooms for 2 nights
5 rooms × 2 nights = 10 Room Nights
Example 3: Hotel Capacity
Your hotel has 50 rooms. In January (31 days):
50 rooms × 31 nights = 1,550 available room nights
Where Room Nights are Used
| Use Case | Example |
|---|---|
| Occupancy Calculation | Rooms Sold (RN) ÷ Available (RN) = Occupancy % |
| Group Bookings | "Wedding block: 200 room nights over 3 days" |
| Corporate Contracts | "Company commits to 500 RN/year" |
| Revenue Tracking | "Total revenue ÷ Room nights sold = ADR" |
| Forecasting | "Expected 2,000 RN this month" |
| Channel Performance | "OTA delivered 300 RN, Direct gave 450 RN" |
Room Night vs Guest Night
| Room Night | Guest Night |
|---|---|
| Counts rooms occupied | Counts people staying |
| 1 room, 1 night = 1 RN | 2 people, 1 room, 1 night = 2 GN |
| Used for RevPAR, ADR | Used for F&B planning |
| Primary hotel metric | Secondary metric |
Available Room Nights Calculation
