it'll take you more than 2 hours to get from san diego up to TRE via PCH. Hell, you can't make it on the freeway unless its 3am.
Girls are everywhere on the beaches, but realize that June is not a good beach month in SD (or LA for that matter). Cataline Eddy makes his annual appearance, and it is usually overcast at the coast.
I grew up surfing various spots in La Jolla (well, as soon as I could drive there...the parents weren't rich enough to live there). If you're from back east pretty much any beach will work for you though.
Mex food abounds...but don't eat any crappy amerikun mex. Find a corner shack almost anywhere. Get some carne asada. Lather, rinse repeat.
The zoo is cool, as is most of balboa park. Touristy, but mellow and beautiful.
If you guys like it now, you should have seen it in the 60's and 70's before everyone and their uncle moved there
