Voted best campground in San Diego every year. The campground has everything - store, restaurant, shuttles to local attractions, bike and personal watercraft rentals, boat launch ramp, a sandy beach on Mission Bay, and an unbeatable view of the Sea World fireworks every night. They have live music and dancing in the summer, kids activities, and more. Catch a ride to Sea World, or down Grand Avenue to the beach with real waves and the boardwalk. A longish bike ride would take you to Belmont Park to ride the rollercoaster and a few other rides. The place is extremely crowded, with the streets clogged with golf carts, bikes, skateboards and the like. The spaces are rather close but there's some greenery. If they are full, ask about a no-hookup parking space for your RV near the boat dock
Don't come here for the camping - it's literally a parking lot with no hookups. But the beach is gorgeous. You can't beat the prices - spaces are only $5 for day use and $10 overnight. Spend the whole day at the beach, walk around the nearby shops and have a bonfire with your rowdy neighbors, because you're not going to be able to avoid the noise anyway. Don't let your vehicle, including slides, extend past the white lines in the parking spaces, or you will get a ticket. There is a boat launch, but this is the ocean and very different from tooling around Mission Bay in a power boat or sailboat.
