I have already researched all the NP campgrounds in Yellowstone, combed the NP website regarding that and other parks we plan on visiting, and checked by phone with out of park campgrounds, determining that West Yellowstone will be the best place for us to stay for two weeks while visiting the area. Thanks to JackieMac, I have determined the best thing for me to do while in Grand Tetons will be to stay at Gros Ventre, the one campground in that area that does not take reservations but will usually have spots open if you're in line by check out time. I have done the research to know exactly where I'm going to stay during this trip. I suggest that prior to you telling someone their information is incorrect, you also do the research to know what you're talking about. It will keep you from sticking your foot in your mouth by providing inaccurate information because you are only going by your own limited, and oftentimes outdated, experience. If you would have paid attention to my signature line, you would have realized I drive a 38 ft MH and a 59 ft rig, disallowed in most NP and state park campgrounds. I would love to stay in some of those parks, but must always find an outside CG and make day trips by auto.
