Any reason why we can’t book a 2 night stay? We tried to changed the dates still it showing no match .

Make sure the days you pick are days that they are open. I know some days during the week they are closed.

They may be booked!

Depending on when, they maybe fully booked. Try one of the other hotels (cause there is access from 3). Otherwise we usually book in October for March because it does book up quickly.
