A friend made a reservation for 12 of us during the middle of the week. We did an early part of the day which gave us the best deal. The folks here are the KINDEST people around! Matthew drove us (and 'Nana' at age 83) out to the sand dunes and the pick up location, all the way being careful not to get too bumpy for Nana! He even took a photo of our group before we began our adventure!
At the helmet/goggle trailer Tony, Jeff, and Nick were the most helpful. The wind was intense and sand was just blowing everywhere so they let us set up our chairs (and pulled out their own picnic table) behind the trailer so that we could be as protected as possible. They fit us all (kids too) with helmets and goggles then had a 'driver meeting' to go over the maps and safety information. In addition to ensuring our understanding of safety and how the buggies worked, they were just plain nice. They told us about how long they had been with the company, why they chose it, etc. AND, while Nana was waiting for everyone, they sheltered her inside so that she didn't get a sand facial! So sweet!
My opinion is that this is one of the safest operations on the dunes. Beware of other drivers, but Sun Buggie is non-stop fun, with a focus on safety! I highly recommend them should you want to try dune buggy or ATVs.
