I am planning a road trip to visit the wineries of Napa, Sonoma, etc. I live in Las Vegas and I have many questions on how to go about planning this road trip. First, what time of year is best to go. I'm really wanting to go sometime in August, but I'd like to know when is BEST. Second, what is the best route to take? I'm very familiar with southern CA, but past LA I'm clueless. What highways do I need to take to hit the majority of the wineries up north? I'm alotting myself two weeks for this trip. Third, any suggestions on lodging, food, etc. I hope someone has done this before without using tour companies, because I plan on just going with some friends and doing this on our own time without the use of any travel or tour groups. Thanks for your help, it is greatly appreciated. Oh, and if you can guesstimate about how much spending cash I may need for this two week trip, that would also be helpful. Thanks again!
