purchased our tickets through groupon for $24. totally worth every penny and then some. We had Brittany as our guide when we first go there she was very busy with a group of 10 girls in a bachelorette party. I felt like she ignored me when i came up to her but my first impression was sooooo wrong. She made me feel so special! i was celebrating my 27 th bday and she made it a point to let everyone know! this tour was amazing because of her..i felt like she truly cared about my bday and had a vested interested in making it memorable! thanks so much brittany u rock!!! you truly are the hostest with the mostest!!!
