Where to update restrictions
Where you update restrictions depends on your connected system:
If you have a PMS/RMS that syncs inventory restrictions to SiteMinder: Update restrictions (minimum and maximum stay, stop sells, availability, CTA/CTD) directly in your PMS/RMS — not in SiteMinder. Any manual changes made in the SiteMinder inventory grid will be overwritten by your connected system
If you don't have a PMS/RMS, or it doesn't sync restrictions: Update restrictions in your SiteMinder inventory grid (as long as the channel rate supports receiving the restriction from SiteMinder)
Does the channel rate support the restriction?
⚠️ Not all channels or channel rates support receiving restrictions from your platform.
If a restriction for a rate isn't showing on a channel after you've set it up in your inventory grid, check what data the channel rate supports and manage unsupported restrictions directly in the channel's extranet.
About booking restrictions
Restrictions include:
Stop sell: Closes availability for specific dates, preventing any new bookings
Minimum length of stay (MinLOS): The minimum number of nights a guest must book, useful for peak periods
Maximum length of stay (MaxLOS): The maximum number of nights a guest can book, helpful for limiting extended stays
Closed to arrival (CTA): No check-ins allowed on specific dates, often used for busy changeover days
Closed to departure (CTD): No check-outs allowed on specific dates, managing departure patterns
Release period: The minimum number of days in advance guests must book
Set up and manage restrictions in the inventory grid
Only follow these steps if you don't have a PMS/RMS syncing restrictions to SiteMinder. If you have a connected PMS/RMS, update restrictions there — changes made in the inventory grid will be overwritten.
Go to Distribution > Inventory.
Under the room type, find the room rate.
Click on the down arrow [x Connections v] to see its channel rates.
Click on the Rates down-arrow (Rates v) to the right of the channel rate name to open the restrictions drop-down menu.
Click the dropdown menu to toggle between Rates, Stop sell, closed to arrivals; CTA, closed to departures; CTD, Min length of stay, and Max length of stay.
Add or change a restriction for a specific date — simply update each cell individually in the inventory grid.
If you select Stop sell, Close to arrivals, or Close to departures, tick the checkbox to turn the restriction on (an empty tick box means that no restriction is applied). If you select Min. length of stay or Max. length of stay, enter the restriction value.
Click Save.
To make changes in bulk, use the Bulk update button or the lightning button.
View restrictions (stop sell, min stay, max stay, and CTA/CTD
To view your restrictions (stop sell, min stay, max stay, and CTA/CTD) for a specific channel rate in the inventory grid:
Find the room rate.
Click the channels dropdown next to the room rate name (displays as "X Connections" where X is the number of mapped channels).
Toggle between rates, stop sell, CTA, CTD, min stay, and max stay using the drop-down.
View or update restrictions for the channel rate.
Save any changes you make.
💡 Note: You can also set up default minimum and maximum length of stay restrictions when creating or editing a rate plan or room rate (not date-specific).
Set default restrictions for rate plans
⚠️ They won't apply to existing rate plans or dates already in the inventory grid. They will only apply to new rate plans and new dates.
To set default restrictions in rate plans:
Go to Rooms and rates > Rate plans.
Click on a rate plan to edit or click Add a rate plan to create a new one.
In the Restrictions and Inclusions section, set the default restrictions: Default minimum stay, Default maximum stay, and Release period.
Click Save.
💡 If you edit these default settings on an existing rate plan, only new dates that appear in the inventory grid in future will reflect the change. To update restrictions for existing dates, edit them directly in the inventory grid (or in your PMS, if it syncs restrictions to SiteMinder).
⚠️ Important: For some channels or rate types, restrictions such as minimum/maximum stay and release periods cannot be controlled from your platform and must be managed directly in the channel's extranet.
Stop sell specific channels
Close availability for the whole room type, or close availability for specific channels. Only follow these steps if you don't have a PMS/RMS syncing stop sells to SiteMinder. If your PMS/RMS syncs stop sells to SiteMinder, make changes directly in your connected system.
Go to Distribution > Inventory.
Click on a room rate’s down arrow [X Connections] to see the linked channel rates.
Click on the Rates down arrow and select Stop sell.
Tick all dates where you want to apply the stop sell (or remove it to open rooms).
Click Save.
Check if the channel supports receiving stop sells: If a hyphen (-) appears instead of a checkbox, manage the stop sell directly in the channel's extranet.
