Correct. Get into Arches before sunrise - most people sleep in. Hike trails as everyone is leaving for dinner in town. Last trip, we did Devils Garden out on the primitive trail from about 7-10pm with sunset - barely saw anyone. Both times I've been to Fiery Furnace, I didn't see more than a couple of people. Some places will inevitably be busy (Delicate Arch at each end of the day) and Windows for sunrise but you don't have to adjust your behaviour much to miss the hordes. Even Windows at sunrise is tolerable as most people arrive after that.
