Whilst checking examples it was identified that the numberOfRooms property does not have Hotel, or one of its super-types, in its domainIncludes.

As per the examples numberOfRooms makes sense as a property for Hotel. The assumption being that this is an oversight.

There is more than one way to solve this:

1. Add Hotel to the domainIncludes of numberOfRooms

2. Add LodgingBusiness to the domainIncludes of numberOfRooms. This may solve the same issue for other LodgingBusiness subtypes.

3. Add Accommodation as a further super-type of Hotel.
