We went on a mini-vacation to Hollywood this weekend. Drove right under the GoodYear blimp. Don't be fooled by the lack of traffic on the 405. It was about a 2 hour drive.
The Hollywood Sign
Lake Hollywood Park
We stayed at Hotel Angeleno. If you've taken the 405 through LA, you've seen it. Looking down on the freeway from the top floor (they let us barge into the restaurant at dinner time so the kids could see the view).
The front desk had a treasure box the kids could dig into. Blowing bubbles on the balcony over the 405.
