Overview
When channels sell the same room in different ways (like package, derived, or corporate rates), you need to map all these different rate types to a single rate in your platform.
Some rate types such as package, derived, and linked rates do not support any inventory updates because they inherit pricing and restrictions from a main rate managed by the channel. You still need to map all rate types to ensure reservations booked on these rates are delivered and inventory is updated across connected systems, preventing overbookings.
💡 Still set Start updating channel to Yes for these rates.
When to use multi-mapping
Use multi-mapping when:
A channel sells different versions of the same room rate
Pricing and restrictions are the same across all versions
Room specifications remain the same
Example:
Little Hotelier has one "Standard double room" rate, but Expedia sells this as:
Standard double room - SellRate - Hotel Collect
Standard double room - Package - Expedia Collect
Standard double room - Linked - Expedia Collect
Standard double room - Derived - Expedia Collect
Instead of creating multiple rates, map all these variations to your single "Standard double room" rate. This type of multi-mapping is common for properties using the Expedia Traveller Preference program.
Remember: All rate types need to be mapped to reduce risk of overbooking and to ensure reservations are delivered correctly.
⚠️ Expedia (ETP) exception: For Expedia properties using the Expedia Traveller Preference (ETP) program, whether you map both Hotel Collect and Expedia Collect separately depends on your Use ETP derived rate mapping setting. If it is enabled, map both payment rates separately. If it is disabled, map one payment type only, as a single mapping delivers reservations for both. All other rate types (package, derived, and linked) must still be mapped. See Map to Expedia.
When not to use multi-mapping
Avoid multi-mapping when rates have:
Different inclusions: Breakfast included vs room-only rates
Different pricing structures
Different room types: Never map a triple room to a double room
Different availability requirements
Incorrect multi-mapping can cause pricing errors, missing extras and overbooking risks.
⚠️ Linking availability across different room types is not supported. If you need multiple booking options to share availability, use separate rate plans under a single room type instead.
How to map multiple channel rates to one rate
Navigate to Distribution > Channels
Locate your channel under My channels
Click the ellipsis (three dots) > select Edit room rates mapping
In the Channel manager column, select the rate to map
Click the Map to [channel] button.
Select Yes to Start updating channel to begin updating rates, availability and restrictions
Choose the appropriate channel rate from the Mapped to dropdown
Click Save
Repeat for each channel rate you want to map to the rate
For all rates mapped to the same rate, ensure the pricing is Derived and set to Keep rates the same to prevent sync issues.
⚠️ Linking availability across different room types is not supported. Each room type manages its own availability independently. If you need multiple booking options to share availability, set them up as separate rate plans under a single room type instead.
