Love / Attending a Polish wedding on my own (I'm English) [25]

Hi,

Im just looking for some opinions this. Im going to Poland(from uk) to attend a Polish wedding in September. For months ive been looking forward to it bit now its causing me some worry.

Basically I will be the only English person there and the only people I will know at the wedding is the two getting married! Im starting to worry about small things like will i fit in? where do I sit in the church, at the reception?

Part of me says go and if things arent working out or if i feel left out I should just head back to the hotel. But then im not going all the way to poland to sit in a hotel room.

Thoughts?

Thanks in advance
