What do you do about real names etc. and paying on these deals?
Are you all lucky enough to be in a position where you don't have to skulk around like I do?
There's an answer to that although it verges on being a bit complicated - I'm sure someone will explain if you ask nicely.
One thing I notice about many hotels is that the cheap places will never budge on price but more expensive not only have more latitude but trust reception staff to cut the best deal they can when no-one else is about to turn up for an underbooked hotel.
I have sometimes paid cash up front but many hotels don't really like this - they want to be able to charge you for 'extras' later ...
