I guess the OP won't come back and tell us their decision

You've said Edinburgh, so it sounds like you just want a short break.

You mentioned Prague and Krakow and appear to have liked them. I'm suggesting Budapest. February though - cold?

Good time of year for Asia or the Caribbean though, but you sound like you're saving longer trips for retirement. I'd suggest a river cruise if it was a different time of year.
