Add room rental per room via setup > locations. This is the rack rate (for example, for a whole day).
You can also create room rental variations. Do this by linking packages to a location.
These packages are retrieved at package price where you link the correct price.
By selecting the location in combination with the package, automatically the correct room rental is retrieved in the request module and event dashboard.
Quickly edit location rent?
Go to setup > location > location rent. This matrix allows you to quickly process location rent.
