We tried out Gudauri and Bakuriani in February 2017 (family trip). We rented a Jeep in Kutaisi (although we discovered there are many shuttle buses as well) to get to Gudauri. Quite a nice ride in an ever changing landscape.
We discovered an unknown (for Western Europeans) ski area with some 55 km of slopes. It is above the tree levels but on top of the Caucasus.
People visiting are Eastern Europeans as well as people from neigbouring countries as well as Israel and Dubai. Very interesting mix.
The quality of the ski was excellent (lots of powder). Some waiting at the ski lifts, but nothing which really bothered us.
Ski passes are really cheap (some 10 Euro a day), renting material was some 8 Euro per day. The skiing was superb with not too many people in the upper parts. There is no risk for avalanches, it seemed. The pistes were well prepared every day; quite nice. The main difference is the friendliness of the people; they were all so happy that we were coming over from Luxembourg. Such friendly people.

Needless to say we enjoyed the location a lot, even although the whole is a bit rougher than what we are used to in Austria. I wil return with family and friends in February 2018,

Strongly recommended without hesitation.
