Best driving vacation was going up 395 from So Cal to Tahoe. It is so amazing, with the Sierras to the west, and the Owens Valley to the east, as you head north. Stop by Bodie (some miles of dirt road to a preserved mining town), stop by Mammoth Lakes, stop by Bishop (Schatt's Bakery!), Mono Lake, June Lake Loop, dip into Yosemite "the back way" (an awesome place) --- we will do it again and again and never tire of it!
Have been to France three times. First two times (20 yr ago), was just Paris (well, we took in Versailles too ;) ), as sil had a part-time job teaching there and visited family between teaching. She rented an apartment and invited me to come along. It was (as mentioned in a previous post) liberating, to take the Metro by myself, to see the Louvre and Notre Dame Cathedral, and the beautiful sights of Paris. Two years ago we went again (sil had retired from teaching), landed in Paris, rented a car, and drove all over France, visiting her relatives and seeing the country. It was a wonderful trip! Went to the Lascaux caves, and saw other sights as we drove (even stayed in a condo overlooking Mont Blanc, and attended the La Roche Bluegrass Festival). Such a memorable trip!
Another wonderful trip: cruise to Alaska! Left from Seattle, and gone for a week, in September two years ago. Beautiful, beautiful, amazing vistas and sights! (and we brought instruments and met up with other musicians on the cruise, and played music when we weren't out sightseeing)! One I would do again!
