We stayed in a cabin during our weekend at comicon. It was a great place for us to crash. We didn't spend a ton of time in the campground, but it seemed generally clean. It was hard to find our specific cabin, but it was clean and looked very new. Sheets weren't super comfy, but you're staying at a campground, so the height of Luxury shouldn't be expected. We personally didn't get great cell service because it's in the hills, but you had to pay for the wifi, which seemed obnoxious. We also found ants in one of the bedrooms and bathroom on our second/last day. We obviously didn't have food there, so idk what the deal was with that. The staff were all friendly and helpful though. All in all, though, it's pretty decently located if you'd like to go to San Diego without paying San Diego hotel prices. If I ever go to comicon again, I'd consider another stay at Pio Pico.
