Hello there!
I live in Hollywood. It is a fun city. As in any big city, use caution. Hang your purse on your shoulder ,dont carry it in your hand. Dont give to panhandlers. It is better to pay for parking in a lot, than park a bit away, if you dont know the area.
Hollywood and Highland is really fun. Lots to see. Bring your camera.
Melrose avenue is great for window shopping, and checking out all the "COOL" people. To see some stars, go have coffee at the coffee bean and tea leaf on Sunset blvd. in West Hollywood. It is across from a great dim sum restaurant called Chin Chin. Then go have a fun lunch at Mels Diner, it is right across the street, you can walk to it.
You must see Rodeo drive. It has LOTS OF $$expensive stores. Also go to 1 Rodeo drive. it is a beautiful area. Lots of great places to eat.
Back in Hollywood, go check out the Roosevelt hotel. It is said to be haunted by Marilyn Monroes Ghost. It is very swank and has lots of great Hollywood History. If you want to see lots of Hollywoods greatest, go to the Hollywood Memorial Cemetary. You can google it. It is in East Hollywood. Not the best area , but the cemetary is safe and has parking inside.
Dont buy a star map, its a rip off. You will only see big gates.
another great place to go is The Greystone Mansion. its in Beverly Hills. It is really fun.
You can google that too.
Have a wonderful time!
