Wow, I really enjoy reading this trip report. I especially liked the justaposition of some of your ground experiences (YHA Youth Hostel in Perth, Priceline hotels in London, sleeping in the terminal, etc) with the descriptions of First Class travel on BA.....
I still can't decide if you have a lot of money, but enjoy the atmosphere of less expensive accomodations, or something completely the opposite...
Either way, it sure was fun reading.
