Here's a discussion starter that will show some variety of tastes on camping road trips. Some of us probably do not plan routes that include cities, other of us will mix city and country.
When you DO decide to visit places that include cities, it's an interesting question as to how. Again, the variety, yes? Some will say to find an in-city RV park, others will opt for hotels. For us, our RV is a pop-up, which is much more rustic, as you know it's more of a tent on wheels, so it seems a bit weird to pop up in a parking lot or an RV resort type setting. We try to find a somewhat-country solution that's within a reasonable drive of the city we're seeing.
I've recently had to consider this while planning an upcoming cross-country trip, and blogged briefly about it here: Smores in Times Square? or How To Camp in the Big City
. We found a MA state park 30 minutes from Boston, a KOA that's a train ride away from NYC, and a northern VA national park campground near DC.
Would love to read about what you do, or if you avoid big cities on your trips.
