Yes, I know my first response was short--but you need to understand that Hollywood is not the upbeat, great place it is advertised as in all the literature and TV shows--in fact, it is one of the most run-down places in the LA area (along with the areas just a short ways south of town). You will enjoy your trip much more (especially if you need to get from place to place) if you stay closer to the beaches on the west or southern section of town.
Once you get just west of Hollywood, and west of West Hollywood, then the areas start to get better--first there is Beverly Hills, then Westwood, then Santa Monica.
Same with heading south--get way south down by Long Beach, and then the areas start getting good--as you head on down to Huntington Beach, Newport Beach, and Laguna Beach. Just north of Huntington Beach a short ways is Buena Park (home to Knotts Berry Farm) and Anaheim (home to Disneyland).
But people just don't understand the difficulty in navigating LA. The city is over 50 miles (90 kilometers) long--and there is essentially no public transportation system worth anything. Also, unlike most cities in the US, the stuff that a tourist would want to see is not located in one area, but rather is also spread all over the 90 kilometer by 90 kilometer area-and the roads are perpetually jamed. It would be like saying you are going to visit London and while still in London you want to visit Stonehenge, Warwick Castle, Cambridge University, the cliffs at Dover, the Roman Baths at Bath, and take in a game in Portsmouth, while not realizing that there are no trains (and very few buses) in the area that could get you to any of the places you wanted to go (unlike in the UK).
You could essentially spend your entire trip (some say your entire life) in your car just trying to get from one tourist attraction to another. That is why Daawgon (and I) suggest you consider San Francisco instead--or else just go to the places we've mentioned.
P.S. I lived in LA for the first 30 years of my life--and have lived about an hour south of SF for the past 10 years--so I know both areas very well. When one lives in Los Angeles--like I did, one has to take in account how far away things are even when planning what we wanted to do for the weekend. For example, I would never plan on going to somewhere on the far side of town for the day unless I was willing to leave at 6 or 7 AM so that the whole day wasn't used up just in getting there and back. Los Angeles is actually a nice place to live because of all the things you can go see and do--but it is a difficult place to visit because of how spread out these things are.
Write me if you have any particular questions about these areas.
