I used to have a rep come from Israel who kept Kosher and observed the Sabbath. He would move into the
La Jolla Residence Inn on Friday afternoon, as he could walk to temple from there.
I believe that
Adat Yehurun is orthodox. Here are the
walking directions from Marriott Residence Inn and the Sheraton (formerly a Radisson). Further away are the La Jolla Marriott and the Hyatt.
There is also a conservative synagogue,
Beth-El.
