You could still visit Kromeriz - if you have time...
Lovely Chateau gardens - but not in winter:
as a day trip - bus takes: 1 hr 10 min, train: 1.5 hrs; I prefer bus..
If you can get Pegas for $79 (Snydley's suggestion); take it... That would be a very good value for money... especially for New Year's time....
We usually stay at Boucek Hotel in Kromeriz - (cheaper rate than on website..:)
but not over the Holidays....)
Right now booking.com has great rates on Grand for New Year's - but It is Adv. rate, non-refundable.(49% off?) Yes GCEK - not BW; it has a feel of European BW; I avoid them in the US...just not the same. Still, Snydley's suggestion is the best IMO - see what rate you can get.... Full credit to GCEK; just re-read: "on the recommendation of GCEK ..."
