Wisconsin to visit my DD and her kids, though that's the only reason for going - I've never been very interested in the idea of visiting the USA. We did visit Canada, years ago, but I don't know how I'm going to cope with a long flight across the Atlantic these days.
I've been to Prague three times and would return in a heartbeat. Such a beautiful city. I'd also like to visit Vienna and Budapest. European cities interest me more than faraway exotic locations. (Also, I'm terrified of spiders, and I suspect that they'd be huge in tropical paradises....)
