We are also going to visit with old friends in Cody so this is only a change in WHEN we go to Cody. We have a full month planned in Yellowstone/Grand Teton and Glacier so I'm not worried about letting them pick the activities a few days. I'm a organismal biologist (with an undergrad background in geology) so they have had no choice but to experience the wonders of nature 365 days a year for the past 11 years ;) - sometimes they just want to do "normal" things. Believe me they will be tired of having to listen to Mom's prattling on about trophic cascades and keystone predators or the Yellowstone caldera by that point in the trip and need a break.
That said, would it be any advantage to deal with Fishing Bridge for a single night on Sunday and campground hunt Monday morning or should I just go looking for space in a unreservable campground Sunday afternoon? I have no idea how a holiday weekend will change the campground migration patterns.
Holidays and days of the week do not change anything in Yellowstone. The campgrounds are all full, every day of the week from mid June to mid September. Locals do not effect the park's occupancy since there is only a very small population within a few hours drive and those locals generally do not visit the park in high summer. There is no bump in visitation on holidays or weekends. Actually the visitations drop on weekends since many vacationers need leave Friday to return home to be in their cubes on Monday or left for the three day trek to the park after they got off work on Friday.
To get a non-reserved site you have to get in line at your campground of choice and wait for people to leave. If you are 5th in line and only 4 people leave, you are out of luck. Finding a non-reserved site in the afternoon requires lotto-type luck.
