I received their response this morning, less than 48 hours after putting initial request for availability. Unfortunately they are booked, although I inquired for Feb.3-Feb.15. At least some, maybe all duration of my intended stay is not available. I did indicate that I would be joining a gathering of ski enthusiasts that frequent this internet forum.
As I indicated in another thread, it is somewhat tricky booking a hotel room/apartment overseas. Lot's of e-mails, pricey money transfers, miscommunications and timing issues. I guess we are used to instant gratification(confirmation) in this country, others do it slightly different.
I will probably cough out some extra money and get a studio apartment at HausMarco (studio is Euro113 - very pricey). Might have to shorten my stay in St.Anton and split my trip in two with cheaper France or Italy being other part of my trip. or some other Austrian resort. We'll see...
Hotel Dorfblick is another one that responded with an offer of Euro83 for single room.
Other inquiries (at least 10) - no response. Also do not like the idea that room/apartment have to be fully prepaid with virtually no option of canceling/changing stay.
Good luck finding a suitable place for your group and hopefully we'll share some mountainside fun this coming February.
