ECI / LCO (Early Check-In / Late Check-Out)

ECI / LCO (Early Check-In / Late Check-Out) are the two most common stay-extension services a hotel sells: access to the room before the published check-in time, and continued occupancy after the published check-out time. Historically granted free as a loyalty courtesy or subject to availability at the desk, both are now routinely productised — priced dynamically, sold pre-arrival, and inventoried like any other constrained resource, because each one consumes a room-hour that could otherwise be turned over for the next arrival.

Formula

ECI/LCO capacity = Rooms with a stay-over or vacant-clean status at the requested hour
                   − rooms required for same-day arrivals before that hour

Example

A 120-room hotel with a 15:00 check-in and 11:00 check-out is 80% occupied tonight and had 65% occupancy last night. Roughly 40 rooms are stay-overs needing no turnover; the housekeeping team can service the remainder by 14:00. Selling 12 late check-outs at €25 and 10 early check-ins at €30 adds €600 in ancillary revenue at near-zero marginal cost — roughly €5 of TRevPAR on the night — provided the same rooms are not needed to clear the arrival list.

Why it matters

ECI and LCO sit at the intersection of revenue and operations, which is what makes them useful and what makes them fail. On the revenue side they are the highest-conversion pre-arrival upsell in most hotels' catalogues, priced against demand rather than offered flat: on a sold-out turnover day the right price is high or unavailable, and on a soft Tuesday it is close to free. On the operations side, overselling them collides with housekeeping capacity and produces the worst possible outcome — an arriving guest waiting in the lobby because a departure was extended for €20.

Both are also loyalty currency. Chains grant them as tier benefits, and Genius and similar OTA programs increasingly attach them as platform-funded perks, which means a property may be committed to giving away exactly the inventory it wanted to sell.

Watch-outs

Sell against real-time housekeeping status, not the previous night's house count — the constraint is cleaned rooms at a given hour, not rooms in the building. Where the extension is booked through an OTA or handled by the platform as merchant of record, check who collects the money and whether it is commissionable; treatment varies by channel and often surprises properties at reconciliation.
