Great, Thanks for your help. If you had Carte Blanche what would you do? The only reason for Zermatt is we have IKON. What is that saving us?
The only thing cast in stone is arrival in Geneva and flying home from Amsterdam.
We will be traveling with a couple of intermediate skiers who have not skied a lot. So going for more groomers and sightseeing.
So a week of skiing and week of sightseeing is probably the best interaly. One of them has Bruges Belgium on his bucket list.
We probably won't bring skis, just our boots.
Since lift ticket prices in Europe are quite cheap compared to the US, going somewhere else that's not covered by the IKON pass will cost you around $60 per day. For example, a 5-day pass for Val d'Isere and Tignes for that time of year is 265€, which is $287 at the current exchange rate.
Zermatt is a good destination for intermediate skiers. But, there are a number of other places around Geneva that are quite good as well, so you're a bit spoiled for choice. My favorite in the area is Val d'Isere and Tignes, but it's one of the farthest from Geneva. It takes about 3:30-4:00 to get there from the airport by bus. Also, it's quite a high ski area, so it can get a bit cold mid season. I'm sure others will have some good recommendations for places to visit.
Keep in mind that a lot of accommodation in the Alps is oriented toward 7-night stays running Saturday-Saturday. So, planning around those days will give you the most options. Ski rental is pretty reasonable in most resorts. There should be loads of shops wherever you go with a good selection of skis, so just bringing your boots is best.
Getting from Geneva to Paris is just over 3 hours if you get the direct train, and going from Paris to Amsterdam is only a touch longer. But getting to Bruges involves a change in Brussels and getting on the slow train, which means it's about 2:30 from Paris and just over 3 hours to get from there to Amsterdam. So, your buddy might struggle to convince the group to take the detour.
BTW, a good site to use to get travel details
www.rome2rio.com. I never book anything from there, but I use it to get basic info on travel time and logistics.
