My wife and I are interested in a group ski tour of the dolomites where we would stay at a different location every night. Do you have any recommendations as to reasonably-priced tour companies? We can leave anytime between now and April... what would be the best time of year for ski conditions and especially weather? Also, we are semi-expert skiers and I'm wondering if a group tour would involve a lot of waiting / slow skiing / unchallenging terrain? We are looking for some adventure, hence the idea of ski touring/ trekking, instead of simply skiing.
