yeah we also booked with cosmos/monarch and also dealt with jo. they were really helpful even when i was getting stressed and kept phoning asking loads of questions! they even arranged so me and my dad could travel in the reindeer drawn sleigh together. at no extra charge. we got married on the 30th dec , we did the 5 day new yr trip was good as we got to watch the fireworks on the slopes on new yrs eve. the only thing i would say is that if your guests want to stay sam place as you i would book all at the same time as we had a few problems with them double booking rooms (tho i think it was actually the fault of the k5) any questions you want to ask feel free and have photos i can email you.
we were lucky as it was actually 2 degrees the day we got married so i was fine in my dress thinkmi would of been very cold at -35 brrr did u wear a normal dress? day after our wedding it was -9 and blizzards but the coldest it went to whilst we were ther was -13 ! really cold at the moment over there im gonna freeze!
did you visit the lanino ssnow village when you were there ? thinking of visiting this time. that also looks a nice place to get married. www.snowvillage.fi
