Hi Renaldo,
we are there for half term as well
Went last year with children..
The train transfer is wonderful, so easy!.
We get the dirt cheap easyjet flight late on Friday and stay with friends or in one of the cheap Geneva airprt hotels. Up early and catch an early train to Zermatt, around 4 hours so arrive at hotel for lunch. All afternoon for ski pass and hire shops etc. We also get one of the late trains out on Friday, again stay in Geneva and get another cheap flight back Sat morning. Home for the Footy!(7 days skiing but only 6 nights at Zermatt ££hotels!)
Your hotel is excellent, looked around last year, its on the main street. Looked very child friendly.
Behind your hotel is the outdoor ice ring. Kids have shopping trolley type things so they don?t fall over!
Next to this last year was a pair of trampolines with sprung harness's, so when the kids bounce they go up around 15 feet! Had to limit the kids due to ££ but ours had a great time.
The ski school LIZS mentioned is excellent, the best I have seen for children. They only start at 5 tho so our youngest is with Stoked, (she is only 4) They both meet at the other end of Town, so a free bus ride(interesting..) or anelectric taxi (£10) is needed. Walking is possible if you leave your skis. About 15 mins. Depends on you children..
The skiing is fantastic, the views awesome, have a graet time.
Good luck!
