Between mid-June and mid-August you will need to have pre-booked. Being a resort town, Napa offers a plethora of accommodation, with everything from unlicensed rooms to top-end hotels. Rooms generally reflect the fact that many visitors only use them to sleep in (or sleep it off in). Most are clean but plain (sometimes dated), with prices somewhat inflated across the board. Independent travellers will be welcomed if there is space (or shuffled off to a buddy hotel), but expect another price hike for just rolling up. Many hotels along the coast only operate from March to October.
