Ideas for weekend trips from San Diego?

I've lived in San Diego for four years, but I still have not seen very much of California and the rest of the Western US.



I'm looking for suggestions for some trips my girlfriend and I can take for long weekends (Fri-Sun or Sat-Mon).



These are our requirements...



- No more than 5-6 hour drive from San Diego each way, or no more than 2 hours by plane. We really don't want to spend more than half a day traveling each way.



- Been to Vegas many times, so don't suggest there.



- Nowhere in Mexico.



- National parks and scenic areas are great, but there must be some decent hotels nearby (no camping or cabins).



- We can't afford five star hotels and restaurants, but we're okay with spending money on "higher end" (3.5 or 4 star) places.



Any suggestions would be greatly appreciated!Ideas for weekend trips from San Diego?

Laguna Beach is a nice place to relax and chill and not far from San Diego.
