You can fly into either San Francisco (SFO) or Oakland (OAK). Both airports are perfectly nice and your choice will primarily depend on the airline you select.
We recommend renting a car. Although Calistoga has so many options in walking distance from your hotel (restaurants, breweries, ice cream shops, etc.), a car will be necessary to get to and from wineries. Unfortunately, the supply of Ubers has decreased.
Although we love the mini versions of you, the wedding and reception will be adults only. We want you to enjoy all that Wine Country has to offer so let loose and relax!
High of 69/Low of 39. The days are nice and warm, but the nights definitely cool off! It is best to dress in layers and bring a jacket with you for night activities! There is always wine available to keep you warm! Since most of you are coming from snowy states, we think you will enjoy this upgrade!
