As far as I can see the future Doubletree is a hotel called Point Hotel Edinburgh at the moment ( hope my information is correct ). As a test I tried to book a room in March which is possible. They accept bookings till first of April.
So my advice is to contact the hotel directly and ask about the status of the reservation.

In case you prefer to cancel - I had a non-cancel reservation and could not cancel through Hilton. But the hotel allowed me to cancel and returned my money.
