Unfortunately, not been there either, haven't been to Austria many times. That resort looks a lot better, much more ski area and looks to be suited for beginners too
I think you're heading in the right direction
I don't like the major resorts, Lift passes are stupid priced and you have to queue half the time for the lifts. As this is your first time, I guess you don't need masses of km of slopes, so somewhere that is suited to beginners will be good. and if the hotel is good, I'm sure you will have an amazing time
