Tours & Activities supplement for single occupancy rooms

It often happens that there are 3 people in a private group. One of them wants a single room whereas the other two want a double bed room.
Prices are usually calculated on a double occupancy base, so one needs a feature to add a supplement for single occupancy.
Is this feature already implemented in Tours & Activities?

Hi,

The upcoming Experience plugin has a new featured called "Single supplement", however it is used for charging a supplement for single guest.

In your use case, you can use the Extras system to create single supplement instead.

Regards,
