I was referring to La Jules Verne. I just noticed you asked about two different places. Happy Travels!

photobear--For Altitude 95, you go to the small kiosk and check in. They check your name against the reservation list and then you purchase your elevator tickets right there. Then you proceed to a special line for the elevator. It is the normal elevator, but once you are in that special line, they put you on the next elevator that comes. So it is sort of like getting head of line privileges. Arriving about 15-20 minutes before your reservation is good.

Is there a special line for Le Jules Verne? We are planning to go our next trip to Paris and I can't wait. What a B'day present!

Jules Verne has its own elevator and it is unlikely that there will be a line..

We show up early for our reservations for lunch at Jules Verne as window seating is obviously limited. We have had wonderful views each time we have gone - don't know if that is luck, or being in that first elevator load.
