We stayed at Bridge Bay, dry camping not too far from Fishing Bridge. We were able to take showers near Fishing Bridge (pay showers); for our upcoming trip, we are staying at Canyon (2 showers per day included in their rate). We didn't miss the hook-ups as we were out touring almost all day; used generator during allowed hours when needed, and used the dump station once during our 7 day trip (you can really conserve water if you want to!). There is nothing better than waking up and realizing you are right in Yellowstone! Stay in the park; make your reservations now.
