Thanks for your reply. I did not think it could be done either.
It is curious, the number of off kilter solo inquiries I get. Maybe to do with the times.
I actually cater to solo travelers (by my ricing structure) in this and another unit as I get many solo guests who come to our universities to work for periods of from a week to a month. They are always great guests. I deliberately created a price-structure so as not to price-out solo travelers.
However, lately I've received a number of both inquiries and IBs for a one person booking, and they reveal no information about themselves or the purpose of their visit. After a little communication it is clear that they are trying to book for one while intending to bring more than one (without paying for them) and for what purpose I don't know.
It's not difficult to get rid of them, but I find it wearisome at this time. I will probably just raise the price to price out solo travelers for the time being: the universities are all closed for the foreseeable future.. I don't mind resting the business during this time of pandemic. Any bookings coming in at this time I will look at very closely.
