From the way it's worded, I think "CO Hiker" is referring to Mt SJ, but "guest" is right that Mt San Gorgonio is fairly close as well.
For SJ, since the tram will be closed on the weekend that you are here, there are multiple trails you can take from the West side to get to the peak:
Fuller Ridge/Pacific Crest Trail
Marion Mountain Trail
Deer Springs Trail
Seven Pines Trail
Devil's Slide Trail
This map
http://www.parks.ca.gov/pages/636/files/MtSanJacintoSPmap.pdf sShows all the relevant trails with their respective mileages. Many people prefer the Marion Mountain Trail, which, although steep, is the shortest non-tram route to the peak. If you're used to the Rockies this should be no big deal for you.
The Fuller Ridge trail will probably give you a lot of solitude, but it has the reputation that the builder was paid by the mile. Many people get very frustrated by this trail because it meanders all over heck and back en route.
If you're in good shape and want a long tour, you could head up the Devil's Slide Trail (DST). This is probably one of the most popular trails, although not too many will take it all the way to the peak. Using the DST, you can access the East side of SJ, maybe even making a side trip to Round Valley which has a nice meadow -- an area that will have very few people in it due to the tram closure. There is water available at Round Valley, probably the only water on the mountain on a route to SJ during this drought we're having.
Anyway, there you have it, a few factoids.
