Booking hotels and attractions in London

I have just found a good website for booking last minute London hotel rooms along with some of the more famous London attractions. I think this is great since I know when I arrive that I’ve already got tickets to the things that I want to see the most. And I get a good deal when I buy them in combination rather than separately. Now I just need to decide when I can take my next trip to London and what I want to see while I am there. I think I might have to wait until there is a good deal on the airfare though.
