All depends on the area and time of year. I workamped in Portland, OR for the past 4 years. We have the largest park in the area and in July and August, we are sent folks that came to Portland without reservations from all our competitive parks. Most parks in our area only have 100-125 sites and are always full in those months. Somehow we find a place for them, may not be exactly what/where they want but it's a spot with utilities! It always amazes me the folks that travel holiday weekends dropping in wanting 3 sites side by side, by the pool, without trees for the satellite!!! :B
