Some are; some are not.
We still like to get out and see the world. Then I will do lots of research on what to see and do. Not that we have to (or
will) do all of it; we've always avoided the "if it's Tuesday, this must be Belgium" mode of travel and on Day 3 of the "gotta-see-it-all" vacation bodies just hurt too much to make it enjoyable. We simply like knowing so we don't return home and kick ourselves for being quite close to someplace we really would have enjoyed visiting -- had we known about it. And we'll push a little to see more. Very little TV-watching when we're in a hotel room in Paris.
Increasingly, though, vacations are more free-form. I recently took a day-long road trip with my second-best friend in the world. No rule other than we had to be back that evening. We headed to a part of Wisconsin neither of us had ever visited. We stopped along the way wherever it looked interesting. We decided on the fly where to eat lunch (okay, there was only one place open in
that town but we could have driven on). We had a fabulous no-stress time, even if we didn't see anything that would show up toward the top of TripAdvisor's list.
Several months ago, DW and I drove down to Austin, Minnesota, for overnight. We just wanted to get away from work, the dishes, and the dog. Really nice hotel rooms (ours had a hot tub) are cheap there. Austin has a couple of attractions but not so many that you feel obligated to see them all. We ate at the hotel restaurant for dinner (probably could have found better food, but research and driving around? not this time). We visited the SPAM Museum (really) and some antique and book stores on their main street, and drove home leisurely. It was just the break we needed and a lot cheaper than flying to Chicago or Kansas City.
Lately we haven't been on the big trips. That's been OK -- the trips we take still are restorative.
