Palm Springs isn't exactly close, but do-able for a one day trip. Depending on where you are going in L.A. it could take around 3 hours (less if the traffic cooperates, more depending on location or if traffic doesn't cooperate. San Diego/Carlesbad would be similar, maybe longer. I'd consider Oxnard if you are going to someplace on the north side of L.A. It all depends on where you are going/doing. If LA is your destination, perhaps you should be looking at motels/hotels instead of timeshares. There's certainly enough of them in and around LA.
