I am with Eujeanie on this. I have cancelled way more bookings than I have stays, for similar reasons. Often it is pre-booking stays for the future as a placeholder that for various reasons I end up not using. I have never had any negative feedback over the years, but this type of activity would be pretty easy for the hoteliers to track if they cared. In the end, the hoteliers set the cancellation rules and I abide by them so I don't feel too bad.
