I'm staying again tomorrow night.
Booked using a pre-pay rate so I'm betting they haven't taken the money yet as with every other pre-pay rate I've booked recently.

Have gone for Room 646. Corner so probably the same shape as last time when I was in 746 (TV wasn't facing the bed so had to pick it up, turn it around and put it on a table). Hopefully some runway views / Concorde although it will be dark so probably won't see a lot anyway - better standing outside the tube station as you practically touch the planes there.

The Doubletree isn't that bad. Do like the Tesco across the road - handy for getting snacks if you don't want to pay hotel prices.
