Hi,
I was lucky enough to have spent a whole week above 3,000 metres before I first 'did' Mt Blanc, unguided, by the voie normale.
Whatever people say, there is quite a high failure rate, because guides (who are both fit and acclimatised) schlep up to the summit with their clients after just a night at altitude. The client is already tired after getting to the hut at guide speed, and has a blinding headache!
It's not the best way to start, finish, or remember your first alpine tick. Do you want to just get up it, or enjoy it?? You choose.
So, what can you do? Well, you could pay a guide to take you up the bossons glacier, practice crevasse rescue at 3,000 metres for a day - whatever- and then take you down again the following day. Rest for a day, in the valley, and then go for the attempt. What I'm suggesting is adding an extra day of acclimatisation at the 3,000 metre contour. A lot of people fail because they're not acclimatised - and that hits hard if you're genuinely fit - which you should be, it goes without saying!
