My 23 year old daughter and I only have 10 days. Were thinking of either traveling to Lisbon with a road trip to Porto or perhaps Spain, or to Budapest with a road trip or train to Prague for a couple of days. Have never been to either country, but have traveled to many other countries in Europe, Asia, and Latin America. We like to do our own thing -- no packaged tours. Both Hungary and Portugal have so much charm, and are known for their food and bars. Both countries seem like they would have similar costs. Any advice?
