You could try contacting Nikola Markov who looks after the Grand Monastery (at mid station)to see if he has any availability.
I will send you his email address seperately
Cheers
That's great - thanks for all the replies. I have passed the details on to the families concerned and hopefully they will get sorted.
We can do them accommodation at Snezhanka but they would have to move out for New Years Eve which is a bit of a pain but we had taken bookings from the hotel as an overspill.
Cheers anyway
