Per the venue website and other sources there is a total of 4,300 seats (real seats and then space on the lawn for 'festival seating'). That's a decent number of seats, but it is far from sold out at this point. Ticketmaster is cagey so it's hard to tell how many reserved seats have been sold. They are showing 2-3 seats in every reserved section....
I'd love for them to sell this out....but unless they get off their asses and promote it more...
So far John Legend and Santana are the only ones sold out, and for two nights apiece.
I like this part:
The Chateau Ste. Michelle wine shop is open before all concerts with wine and picnic items available for purchase. In addition, an array of food vendors will offer a selection of menu items for sale in the amphitheater. Concert-goers may also bring their own picnic baskets and non-alcoholic beverages. (The Washington State Liquor Cannabis Board requires that all alcoholic beverages consumed on the winery grounds be purchased at the winery.)
