Sometimes it just feels like being "nickel0and-dimed" to death, except in fairly large amounts. Thankfully, Denmark is part of the Schengen zone, so at least that's not a worry. And the place we're staying is largely paid for.

Our biggest expense tends to be paying someone to house sit and mind our pets while we're away, and then the cost of keeping all the bills paid at home because we're self-employed and there's no such thing as "paid holidays" in the USA.
