I have never been to San Diego, but my hubby has twice. Both times were business trips, so his company payed for everything, so I'm not sure on the pricing, but here is the names of the hotels he stayed at.
The first one he liked ALOT:
Catamaran Resort Hotel
3999 Mission Boulevard
San Diego, CA 92109
800.422.8386

The second one he said was out in the middle of nowhere except for a winery close by:
The Hilton Garden Inn San DIego/Rancho Bernardo
17240 Bernardo Center Drive
San Diego, CA 92128
1.858.676.1660
