Pokestops in and around the San Diego Convention Center

Gonna be doing a lot of line waiting at SDCC, does anyone know how many pokestops they've added since last year? I have an idea of the gyms I can access for items but the pokestops specifically are what I'm curious about.

I remember there not being all that many pokestops and I'm gonna need to restock on items hopefully without straying too far from the convention center. If someone has current info on that I'd really appreciate it.

Thanks!
