We loved our tour! We did the after hours (5:30-10:30) tour which was great timing, the breweries were busy but we got to sneak away to the back to get a full experience.
At first, I was a little skeptical about spending $100 just for a brewery tour, but it was well, well worth it. There's four stops (I'm assuming they change by day/week/etc) and each stop offers 3 or 4 tasters.
Eric was our tour guide and he truly made the tour awesome. He was great with the schedule, giving us ample time and notice to use the bathroom or how much time was left. He kept it fun on the ride between breweries and checked on all the groups if we were split up during stops.
I'd highly recommend reserving a spot for a tour in whatever city you're in!
