We are an Irish couple that would like to get married in Zakopane in Januaray.
You may want to consider having the church wedding only in Poland, to get the civil side done you will require a lot of paperwork.
Here are some places to look at for ideas,
The wooden church in the town of Witow is absolutely stunning,
This Karczma is excellent the prices are not cheap for Poland, although the quality is very good, I have eaten here many times and always walked away fully satisfied
Villa Tatiana is a great place for your guests to stay, the people that run the place are very nice people and real Gorals.
