CTD (Closed to Departure)
Definition
The mirror image of CTA: a restriction that blocks check-outs on a specific date. Guests can stay through that day but can’t end their stay on it — CTD on Sunday means a Saturday arrival can’t book Saturday-only, the stay must run at least through Sunday night.
What it tells you
CTD pushes occupancy into a soft night that follows a peak. If Saturday sells out on its own but Sunday runs empty, CTD on Sunday converts one-night peak demand into two-night stays instead of leaving Sunday to discounting.
How to track it
Set per date in the PMS or channel manager, typically on selected rate plans rather than house-wide — it visibly narrows the guest’s options at booking, so it costs some conversion. Remove it as soon as the shoulder night has filled.
Where it fits
The less-used sibling of CTA in the length-of-stay toolkit: CTA protects the peak night itself, CTD stretches its demand into the night after.
