Wow, that's crazy! I know the Regent's Park Marriott was going for bids of $78 for the night of Oct 13. If your stay was longer I'd suggest splitting it into 2 stays and being open to switching hotels because the deals can be in different zones for different nights, but with only 3 nights that's hard to want to do. I also really like the Notting Hill zone, it's still very central on the tube and a lot of fun. I would consider bidding there next if it were me. Take a look and see how pricing changes for each night in different zones with Express Deals, it might give you an idea of what the holdup is. What I have done, and only in times of desperation, is to look at staying in Kensington or Chelsea. If you stay in Chelsea it is likely the Copthorne Football Club hotel that you'd get. The location and hotel are decent enough though not top-tier like the other zones, but I must have saved at least $30 a night the time we stayed, and we had 3 rooms. We split our stay and went out there for the expensive night, it was worth it for us. I'm hesitant about Kensington. The location is great, I LOVE Kensington, but they have upgraded the Copthorne Tara to 4* (worth checking the listings in case they put it back down to 3* in which case the zone is back to being okay!). It's got good transit links and is fun on its own merits. The non-Tara hotels in Kensington are all pretty good. I might pick Finsbury first though if you can get a good price, it is still close to the action and the 2 known hotels are good ones, but it doesn't always come cheaply. City/London Bridge zone borders Westminster and is usually the same price, I'd be open to that one if the deal was good. Hammersmith/Wembley/Richmond are too far. Docklands is a ways out as well but it has good tube links, though one of the Hiltons they may use is on the riverfront and I think you have to use the hotel's water taxi to get to the tube, the other hotels are well linked though. Anyhow, those are just ideas for when desperate measures are needed!
