I work away every 3 weeks or so and stop out on my own (sales rep), so work pays for hotels and meals etc.

My question is, if I want to bivi while working away I'd feel silly just using the hotels for a shower and a change in the mornings and it's such a waste of money.

What's the best way to get work ready in the morning?

Quite a few swimming pools do an 'early bird' type thing ... turn up, pay your money and use the showers, etc. I once spent 12 months living like that ... I actually became quite good at swimming too.
