Hotel MLOS, CTA & CTD Restrictions Guide
Master Minimum Length of Stay (MLOS), Closed to Arrival (CTA), and Closed to Departure (CTD) inventory rules to protect weekend RevPAR.
Quick answer
Inventory restrictions—Minimum Length of Stay (MLOS), Closed to Arrival (CTA), and Closed to Departure (CTD)—control booking patterns across distribution channels. When applied during peak holiday windows and festivals, these controls eliminate unbookable single-night gaps and drive higher multi-night RevPAR.
Editorial note: Ensure your channel manager pushes restriction tags reliably to all connected OTAs to prevent unauthorized single-night booking leaks.

The Strategy Behind Inventory Restriction Controls
Most independent hoteliers rely exclusively on price adjustments to manage revenue. When demand rises, they raise rates; when demand drops, they lower them.
However, price adjustments alone cannot solve structural stay-pattern problems. If you sell all your rooms for Saturday night to single-night travelers, your Friday and Sunday nights are frequently left stranded with 30% occupancy—a phenomenon known as orphan nights.
By mastering Minimum Length of Stay (MLOS), Closed to Arrival (CTA), and Closed to Departure (CTD), hoteliers can systematically engineer profitable multi-night booking patterns.
The Difference Between MLOS, CTA, and CTD Controls
| Restriction Tool | Operational Definition | Best Use Case | Risk if Misapplied |
|---|---|---|---|
| MLOS (Min Length of Stay) | Requires reservations spanning a specific date to meet or exceed a set night threshold (e.g., 2 or 3 nights) | National holiday long weekends, New Year’s Eve, major festival dates | Over-restricting during low demand blocks high-value 1-night business travelers |
| CTA (Closed to Arrival) | Blocks guest check-in on a specific date, but allows guests checking in earlier to stay through | Peak Saturday of a 3-day weekend; Christmas Eve; major wedding dates | Inadvertently prevents bookings if nearby competitors accept same-day arrivals |
| CTD (Closed to Departure) | Blocks guest check-out on a specific date, requiring the stay to extend at least one more night | Sunday mornings during 3-day holiday weekends (forces Monday checkout) | Frustrates travelers bound by firm corporate work schedules |
Channel Manager Sync Integrity
Ensure that your channel manager supports 2-way restriction synchronization. Some budget channel managers update room rates and availability but fail to push CTA/CTD flags to MakeMyTrip or Agoda extranets.
Strategic Implementation Rules
1. The Long-Weekend Formula: Friday Check-in + 2-Night MLOS
Whenever a public holiday falls on a Friday or Monday, enforce a mandatory 2-night MLOS for all reservations originating on Friday or Saturday. This guarantees that your property captures full weekend value without suffering a Sunday vacancy cliff.
2. The Saturday CTA Anchor
Apply Closed to Arrival (CTA) on Saturday night across all OTA extranets 30 days prior to arrival. Any guest seeking a room for Saturday night is forced to search for Friday to Sunday (2 nights). If unbooked rooms remain 3 days before arrival, lift the CTA restriction to capture last-minute high-rate spillover.
3. Review Verified Holiday Dates
Check verified holiday dates using our free Hotel Demand Calendar to align your MLOS and CTA calendar rules at least 60 days before peak holiday windows begin.
When Applying Restrictions Can Hurt Hotel Occupancy
While restriction rules are powerful during peak holiday compression, overusing them during shoulder or off-peak seasons can severely hurt hotel occupancy. If market demand is sluggish, demanding a 2-night minimum stay simply drives flexible bookers to nearby competitors. Apply restriction controls only when advance pace confirms that demand will comfortably outstrip available room inventory.
