I did some further research on my above questions. Following are the details i got, the same will be useful to others:
1) Tyrolienne (1 flight) CHF 20 adults CHF 15 children ;
Ski- and Snowboarding CHF 35 adults, CHF 25 children ;
sleddingpark CHF 15 adults CHF 10 children ;
a one day pass for skiing, snowboarding and sledding is CHF 45 adult CHF 25 children
If you dont want to experience any skiing or snowboarding then you just get the tickets for the sleddingpark for CHF 15 per person. The fee is for the whole day. But usually people don’t stay much longer than an hour or two, that is same cost. If it is very busy and crowdy, sometimes there can be a waiting line for the tubes…
2) As above
3) The entry ticket you can buy outside at the glacier, right at the info desk at the snow fun park, which is only open if good weather, from around 10 am to 4 pm.
4) There are no other activities, but attractions to visit, like Ice Palace, Sphinx Terrace, Alpine Sensation Tunnel, the Plateau, Lindt Chocolate Heaven exhibition – there attractions are all free of charge
5) There is a small area right next to the cafeteria where you can picknick and eat your own food, but there are no tables there and you have stand or sit down on the ground. We have 3 restaurants at the top : Crystal Restaurant, where you get served, then a self-service restaurant and an Indian restaurant with buffet
6) The hike to the Mönchsjoch hut takes around 50 minutes to get there and around 35 minutes back. It is a trail on snow, you need good shoes to do this hike and at the hut you have to climb up on a snowy/icy stair the last steps. The hike to Mönchsjochhut is possible for everyone, but, it is on 3500 metres above sea level, and on snow. People who are not used to hike up in to the mountains maybe get tired quick and the air is thin. They can try and if they get to tired they can stop the hike and turn around.
In case there is any additional detail then plz add..
