Ken and Shiela,
We've stayed at Swee****er Regional Park.? You need to know it's also a park for horsecamping so there will be horses there.? When we stayed there we had the horses and a truck camper.? I wasn't all that impressed.? If I remember the sites are small.? I can't remember any hookups either.
There is another relatively unknown park off of Highway 52 near the #15 & 52 junction called Santee Park.? They have full hookups.? It's not as lush as Chula Vista; but it's in a good location, is a lot less expensive, is gated and near Mission Trails Regional park which is a nice place for hikes.? It's more north of San Diego whereas Swee****er is east.?
Let me know if you need any more information, we live just north of San Diego.
