I've stayed at this hotel many many times and they've never agreed to amend my booking so that I pay just for one person citing that it's only applicable for full rates - which no one pays. Do you just select one person when booking then add a guest?
I booked online at hilton.com and selected one guest. i never added a guest online. we simply arrived there and checked in. it was clear that there were two of us as we gave them both of our passports.
The subject of there being two guests on a booking for one never arose.
