This is a great report and terrific photos. Took me right back to my own Alpine adventures, when you get the weather window as you did it's a truly magical place, but it doesn't half look crowded on your ascent day
. Lot's of queing and multi-lingual muttering I should think
If you ever get to go back you should have a go at Mont Blanc du Tacul. It's not as high or as technically demanding as Mont Blanc and provides great views from its more central position. I climbed it solo without any issues and had the mountain to myself in mid-Summer. Done in one long brilliantly sunny day. Remains one of my favourite mountain experiences.
