We will be in LA on vacation in June. We'll be spending 3 days at Disney and 5 days in the Hollywood area. We've been there one other time so we've seen some things but I'd like to get feedback on a few other places we're considering, which are the La Brea Tar Pits, Joshua Tree National Park, Channel Islands, Death Valley, Griffith Observatory. We'll have a rental car so we'd be able to drive some distance away. We'd like to keep the driving limited to 2-3 hours from the LA area, though. I'd appreciate opinions on the places listed above as to whether you think they're worth going to, and also any suggestions for other places. Thanks.
