All the spots where you can sit down and see the show are staked out long before the show, and there is a good bit of competition for some of those spots, too. They do designate a patio at the northern end of the lagoon as a sit-down-only area, and there's a good amount of space for people to sit on the concrete there. While it has also always been full, in our experience, I think it fills last of all the options.
