We had a wonderful experience with Napa Sonoma Wine Tasting. I highly recommend this company for your driving needs. A few quick tid bits before I provide a long explanation. First, paying in cash will save you the 4% fee that is attached to payments made with credit card. Find out the base fee for the area in which you are requesting that they drive you around in. I believe this takes into consideration the cost of toll, gas, and the like. Then, you are pretty much ready to book once you figure out the hourly rate. I must admit, at first, I was a little worried about this company because I did not hear from them after left the initial deposit. It was not until the week prior to the event I started to hear from one of their representatives. Weeks prior to the day of the event I did not pay much attention to the Sprinter set-up; I left a tentative schedule with a time span of 6-8hrs for the company and that was it. When we got closer to the actual day of the event, I started to worry a bit because I had not heard from the company via telephone. Do not let that alarm you because I guess like most of the world, they communicate mainly through email. I am used to speaking with companies over the phone and hashing out details verbally vs. through email. I could just be an old head when it comes to stuff like that. I did notice they had reached out to me via email to confirm our plans a few days prior to the day of the event. Fortunately, I caught the email in time because I noticed a discrepancy, so I quickly sent a text message and email to their company. They responded immediately. That is another good thing, the company is very responsive through phone and text which made me feel at ease. You should plan your trip well in advance because the winery locations have been extremely busy. As previously mentioned, the sprinter was reserved well in advance of our arrival. I left a small down payment and that was it. My focus shifted on finding the best wineries to visit. I would suggest you spend equal amount of time on the selection of your sprinter/limo. The company provides you with room temperature water bottles. Make sure your group has snacks/food/ napkins, cups, ice, etc. Basically, you need to make sure your guests have food and beverages in the Sprinter as well as a proper way to store the food cooler/ice, napkins, etc. Overall, I highly recommend this company for your driving needs, and I look forward to using them again.
