My favourite spot!

Further advantages include:
1) You don't waste any time packing your kit up pre-summit hike; you can roll out of bed, pull your shoes on and start hiking.
2) Your tent is dry by the time you get back to it post-summit, rather than carrying a wet tent all day.
3) You've had a nice extra dose of acclimatisation
4) You get to feel really smug as you look down at the string of head-torches winding their way slowly up the mountain...
