My client mentioned several times that he's been renting rooms by the hour at London Heathrow and keeps telling me to do the same. I've just had a look at a website daysuse.co.uk and they've got some pretty good deals as well as options regarding time slots i.e 9 am - 3 pm and 10 am to 6 pm.
There seem to be quite a few popular hotel chains that charge anywhere from ?40 upwards for these time slots.
My life is pretty sporadic so I can't always book hotels in advance even though it's the cheaper option .
I think it's a great idea for short notice bookings or If you only prefer to see one client a day
Or like me prefer the warmth of your own bed.

Well JustJennifer i'm gonna give it a try this week and let you know.
