it was very well organised but i would like to tell you only one hour time givens to us on top and most of time we have to run behind the guide due to fear in mind that we will get lost. drop time can be extended late night at ZRH main stations. because we spend lot of money and come to see once in life time. if we dont enjoy it is no point. guide was good but he wanted us to control like controlling pet in the house. due to this we could hardly enjoy.
min two hours time should be given to visitors at the top. other wise it was good trip.
thank you shridhar
