My family will be in Chamonix on July 13th. We are definitely planning to ride both the Aiguille du Midi and telecabines to Helbronner point. I am confused about the tickets. Can you buy a ticket for both together or do you have to buy a separate ticket once you get to the top of Aigulle du Midi? As long as we arrive early, can we get tickets the same day? (We are on a round trip through France and I am not sure I will have access to the internet in the days before our arrival in Chamonix to make reservations) Do the gondolas to Helbronner point ever "sell out" or are you pretty much guaranteed to go once you get to the top and are willing to wait in line? Does anyone know if they take credit cards or is it cash only?
