Just to clarify, I was not so much questioning spending extra hours in an airplane to gain miles (a whole separate topic, as one said...to each his/her own).
Rather I just noted the irony of flying thousands of miles and then looking for the cheapest shower available.
I will be the first to admit this is a phenomena I neither understand nor envy, but do enjoy learning the motivations of others.
Hope the 'mileage runners' did not find this offensive.
