Some general information about YNP (some points apply to GTNP also). (snip, snip)
I'm not quoting the entire post above, but it's all good advice. We just left Yellowstone a couple days ago via West Yellowstone and one thing I'll add. At around 9:00 to 9:30 a.m., the road inbound from West Yellowstone to Madison was 14 miles of nonstop bumper-to-bumper cars and RVs creeping along at 25 mph. And the gate at West Yellowstone was three lanes wide and backed up for a long ways. I'm not sure if this is just normal summer traffic, or this was just an aberration, or if some times are better or worse than others, but thought I'd pass it along in case it's possible to plan around it.
Despite that (and all of the buffalo jams, gawker slowdowns, bus loads of selfie-happy tourists, and all that), Yellowstone is such a great place that all of the issues seem like just petty annoyances. I love that park.
