The hotel in question is next to Tower Bridge and backing on to St Katherine's Dock. On day one, I worked and found time to tour the docks and having done so return home.
The following day I worked a full day, took in some views of Tower Bridge, and returned home.
On the third evening, I stretched the test. After work and what's more after dark, I joined fellow delegates for a delicate evening of champagne guzzling and mini burger scoffing at a wine bar across the river.
After said guzzling and scoffing I was still able to make my way home with a meander through a London nightscape.
On the fourth day I told Mr Him of my adventures and conclusions. I now need to write up my experiment with results, statistics and the controls for him to give his employer when he's asked to stay again.
