Another vote for the 3 Ms and if you don't want to cart a load of bivi stuff around, just doss down in the Midi station until midnight. Taking a foam mat or similar to lie on makes things a bit more comfortable. The best spot (warmest) is on the stairwell that leads to the observation platform that looks over the 3Ms. Leaving early also ensures you are well clear of the 2am rush from the Cosmique Hut.
