You have to buy the Groupon and then go to Davys website and make reservation using the code on your Groupon tickets. If that time is available they will allow you to make the reservation and will send you an email confirmation. Or you can go to their website and see if the time you want is available. I didn't have problem reserving my time but I made it 4-6 weeks before the date I reserved.
I did mine on tbe website. It was very easy.
Catherine is correct.
Catherine's explanation was correct. There is however, a small fee when you reserve.
I called first and they let me know how full my time slot was
