Accomodation in Passo Tonale

I found cheap Ryanair flights for six of us flying into Bergamo and then car
to Passo Tonale (Thurs 26th Feb to Mon 1st Mar), however cant get anywhere
to stay. None of the travel agents are able to help, since its not a full
week. I phoned a couple of hotels, again they want the full week.

Anyone have any contacts or ideas

Thanks
