I hope you enjoy sitting in pubs all day because that is what is on the menu in December. There might be snow then, but most likely it will be dirty slush. Our mood goes down but it will be interesting when you later post how dreary Poland is.
It will be an expensive mistake given you have a choice to come in
regards from Mexico :)
Happy belated Cinco de Mayo
, btw. Bet you didn't know that the holiday was established after the national tragedy some time ago. The Mexicans, being true lovers of Hellman's mayonaise, were so distraught after the sinking of a whole freighter of mayonaise heading for Mexico on the 5th of May that they established this holiday. I bet you learned something different in school, but now you know the real story. :)
