In reply to GridNorth.
that makes a great day out if you are quick.
As its the OPs first trip even if they spend a day sat high on the rouge just looking out it wouldn't really be wasted time.
First time i did the chappelle we enjoyed the view too much over lunch and missed the lift by 5 mins. with my dodgy knee at the time, that long descent was hell.
to the OP. get day tickets for the lifts and use them.
