I don't actually have a sauna in my apartment, although it's very common to have one even if the apartment is quite small. I live in a rowhouse with 8 apartments, and there's a communal sauna (another very common setup). Since there's only a couple other people using the sauna, we don't have a reservation system in place nor do we pay for using it, but other places have either a paper on the notice board or an online system for reserving shifts, and in those cases it's usually charged per use once a month. My parents live on a small farm and have a smoke sauna, which is very traditional. I've been to saunas heated with wood and electricity, small private saunas and large communal ones, plus a tent and a trailer, both made sauna. I could write up something about the sauna culture and/or different types of sauna you can find.

I haven't been to Santa's village, although I drove past it on a trip to Lapland a couple years ago. It's pretty much a full day's drive from where I live, but you could take the train or a plane to get there faster. My wife wants to visit the village, so we might very well go once our kid is a bit older and can enjoy it as well. I could also write a post on the origins of Christmas (or, to be precise, Yule), since that might be more informative and I could do that without making the trip up north.
