Is it reasonable not to let vans park in the open-air parking lot at the entrance of star-rated hotels?

It makes sense that the parking type at the entrance of a star-rated hotel is determined by the hotel. Of course, the management of the hotel's own parking lot is decided by the hotel, and it is reasonable for the hotel not to stop, because the parking lot rent is generally paid by the hotel, and of course the vehicle model is also controlled by the hotel management.
