Napa and Sonoma Travel Guide
Book hotels well in advance. Hotel reservations, always advisable, are generally necessary from late spring through October and on many weekends. To be on the safe side, book smaller hotels and inns at least a month ahead.
Call restaurants ahead. Reserving a table, or asking your hotel to reserve one for you, can save you time waiting at the door.
Reserve at wineries, too. If you're keen to visit a specific winery, double-check hours and tour times and, if possible, make a reservation.
