Here is a video of my wife as we travelled First Class on British Airways for the cost of coach tickets (BA's fees are very high).

We stayed at the London Hilton Waldorf for 5 days for 200,000 Hilton Points before moving on to Belgium.
Just thought I'd remind everyone and more honestly, all those looking around and saying why would we do that. Why spend the time and effort with the points game... this is why.
