Hilton Garden Inn San Diego Old Town/SeaWorld Area {US-CA}
All new hotel to open in San Diego in October 2015. Still some rooms available late 2015, early 2016 for $98.00. Parking $17.00. Very close to trolley so no car needed.
If you want to take a trip back in time do an image search for the Padre Trail Inn. I never stayed there but now I miss it. Drove by a million times.
