I have been to this place 10 years back, and I had enjoyed the gondola ride. But what I can definitely say is that the Gandola cable car price has gone up 10x in these 10 years, the price is too high even if it is 1700. But that's okay considering the span of 10 years. But yes, that would have added another beautiful experience to your tour.
As always the photographic shots are neat and clean. It seems like your kids are enjoying a lot and good for them to enjoy such a place at such a tender age. That's like unlimited fun for them.
They have plan to go back :)
