Um...it's supposed to be Camping. Since I've replaced the tent with an RV, I'm in the same boat as everyone else. But I haven't been in a campground yet that doesn't have multiple open tent sites. Which is what almost all National Parks were built to accommodate, mostly. Besides the limiting of impact, which is a very valid point, there is the issue of $$$$ to upgrade, let alone expand, campgrounds. There was no money before, and in this new political climate it is even more unlikely there will be a fresh influx of money.
So to go on a whim, pack a tent. To go in an RV to YNP, plan ahead and make a reservation. The downside of the upgrade to have your own home on wheels.
