elisabeth, luv2gbo37 provided great info.
the map at
http://www.attpac.org looks west.
so, the winspear and myerson are on the left and the woodal rodger fwy is on the right.
the last time i was there, they had nice folding chairs in the main seating area but no tables. just call the box office and see what they can tell you.
just went to
http://www.attpac.org and saw what you were asking about.
i would imagine that those tables are on the same level as the entrance to the winspear, meaning they are 15-20 off the lawn seating level and at a funky angle to the stage. you might miss seeing a band member who'd be on the right side of the stage.
but the chairs they had were nice and comfortable.
and on oct 14, the heat should be gone.
the website just indicated "Limited Availability: Only 5 Tickets Remain"
so you better hurry if you want creature comforts. on $10 more than section 10 and 12.
