Yeah ;-) There are solutions. Members clubs. Plain old hotel rooms. But mostly the price-point is way to high for an hour or two. The overhead and friction in booking and checking in is also substantial.

I've got a Regus gold card. The number of times I've actually used it in the last 18months - zero. Because the friction in actually making a booking and getting something sane out the other end is so high. I find especially memorable the time where I was running on EST in London and wanted to work at night, was told verbally that Regus has 24 hour office space at X address, only to show up to find a confused security guard and no access ;-)

So it seems like a gap in the market to me !
