Where besides Vegas have you taken a solo vacation? Business trips where you spent a few extra days or came early don't count. You wouldn't have gone to that destination unless you had business. I've had about 50 of those. I was into baseball trips for a brief period. I went to Boston, Chicago, Denver and Houston for the baseball and side trips to points of interest. I was impressed by many of the things all of those areas had to offer. If I were forced to pick a favorite, I think Boston would win by a tiny majority. I always wanted to do Anaheim, but never go around to it. It would have been cool to do an Anaheim/Las Vegas combo trip.
