It appears we could add a visit here after a hike around Mont Blanc next summer, as we will be close to Geneva and could fly out of there. According to this website, we can only book individual visits 15 days in advance.
Has anyone here done this, and did you need to book right on the minute the booking window opened? If so, what time was that (in Switzerland)? Midnight there, or maybe 8 am? We would have to do this on a particular day as I will make our flight reservations around this well ahead of time.
Any advice or thoughts on the visit appreciated!
