I'm looking to take the lift from Chamonix to Aiguille du Midi (and then the télécabines to Helbronner - I can't wait). I'm confused about reservations, though. The RS guide says "To beat major delays in summer, leave no later than 8:00, no reservation needed." But then later in the same paragraph, he says, "Reservations are taken from one to seven days in advance (no same-day reservations, usually booked up one day out—try to reserve at least two days ahead)."
I'd prefer not to make a reservation until I get there and see what the weather's like since they're not refundable, but I don't want to miss it, either. Does this mean as long as I get there early enough, I won't need a reservation, or am I misinterpreting it?
While I'm on the subject, is hiking down to Montenvers from the Plan de l’Aiguille on the way back a good idea mid-June, or is it still icy (I feel so ignorant asking this lol).
Thanks in advance for any advice on this!
