I'd go for a vacation to just about any country that seemed interesting, regardless of their view on RKBA.
Here at home is another matter. No Illinois, New York, or California for me.
Hard to explain, but here goes: To me, going to say, Germany or Russia would be a once in a lifetime thing, and there are things there that you just can't see here in the US. It's worth a week or two of not being able to carry. Going to California? Meh. There are other states that have similar attractions that do respect RKBA.
