David & Audra,
We have stayed in San Diego often.
http://www.sdrvresort.com is nice, but tight and there is a light rail behind the park. Not so noisy, but you do hear it. Nice sites with colorful foliage. This park has a pool.
http://www.missionbayrvresort.com is owned by the City of San Diego and they do have restrictions on your 5er and TV - 10 years, if I remember on the 5er and no visible damage on either. No pool, but gated and security. Located between two mobile home parks that are also owned by the City and which is trying to remove them. We actually prefer this one as it is centrally located to what we desire: our kids and grandkids and the beaches. Nice, long sidewalks to walk or ride your bike.
http://www.santafepark.com is tight and only 30 amps. It also backs up to the railroad and is quite noisy.
http://www.chulavistarv.com is nice - we haven't stayed here, but have driven through. We chose not to stay here because it is so far from San Diego, in time more than miles.
