“Budget is a relative term for Sonoma hotels. The least expensive...range from $80 to $130 per night.”
The Sonoma Valley is also known as wine country due to all the vineyards and wineries that call the region home. It's a popular spot for tourism, and for more than just the wine or sightseeing. The most popular time of year to travel to Sonoma is during harvest season which begins in August, but ramps up into full gear during late September. The popularity of the grape harvest may cause concern for those who are seeking a cheap hotel in Sonoma, but there are deals to be had, albeit not in the immediate vicinity of the vineyards. One example is Quality Inn Petaluma.
