I'm travelling to the CR over the Christmas holidays (the 22nd through the night of the 1st of January)... but have yet to find a place in Praha the night of the 30th, 31st and January 1st. Someone told me that the dorm rooms were "rented" out fairly cheaply there. Does anyone have a contact or know who I could make an inquiry with...I'm willing to pay $50-75 per night even, but I would like to have some idea where I will be staying before I get there, because it is the holiday season, and that makes me a LITTLE nervous. I've gone on trips before without figuring all this out and it worked out fine in the end, but it's a difficult time of the year around New Year's in Europe.
