Great
The TUI app was a bit misleading. There wasn't that much information The whole trip lasted about6.5 hours, not 2 to 4. In the winter we needed very warm clothing, the temperature was about 3C and there was a howling wind. The telescope is perched on uneven ground on the side of a mountain, and of course it has to be dark, so you can't se the ground and with feet like blocks of ice, it was easy to stumble. The sunset views before was magnificent, the guide was excellent about the stars etc.
