It was one of the most amazing experiences ever. I tried again in 2017 to get a reservation, and logged into system a few hours after the spots went on sale and sold out again! Determined to go, I set an alarm to be at my computer to be online when 2018 reservations opened up.
It was sold out for the entire year (2016). If I could give this more than 5 stars, I would! A few years ago, I saw this come up in a Facebook feed and it looked liked something I'd love to do.
