Chula Vista RV Resort vs SD Metro KOA
We've stayed in both. We are full-timers with a 43' 5th wheel. We stayed in CV RV Resort from Dec 2015 to Mar 2016. It is immaculately maintained, and if you have a site at the back facing SD Bay, you'll have a great view. The sites are not very large, but we managed to shoehorn our rig into one of the back sites. The marina is under the same management as the RV Resort. Most of the rigs were pretty high end. Our only real complaint was the front office staff were very abrupt and not all that friendly. Also, with our reservation they didn't honor the price that we had confirmed at citing "we have the right to change our fees without notice". This was a bit of a surprise. However, many people return year after year, and we found them to be very cliqueish. Made it a bit difficult to socialize. Don't think they have any tent sites. We were planning on spending Dec 2016 to Mar 2017 at CV RV Resort, until we had occasion to stay at the SD Metro KOA this Fall (Sept).
We really liked the KOA. Bit more of an eclectic group of folks, much more family oriented, and just felt like a more relaxed place to be. We are retired, no children with us, but we really enjoyed the family atmosphere. There are lots of shade trees, and the sites are a bit more spacious than the CV RV Resort.
As a result we changed our winter reservations this winter from the CV RV resort to the SD Metro KOA. The Metro KOA is also a bit less expensive.
My $0.02, and worth every penny.
