Well…Newport Beach is a great place with lots of choices for activities. It has a huge wide beautiful beach which is several miles long. The two piers, Newport Pier and Balboa Pier are beautiful and interesting but also very active at sunset. (Newport Pier is on 21st Street and is the busiest of the two) Consider going farther north on the boardwalk, possibly up around 32nd street area. On that end it is likely quieter at sunset and there are definitely plenty of restaurant choices in that area as well. Have fun.

Laguna has more natural beauty w Rocky beaches and cliffs. Only walkable area is Main Street and PCH. Check to see how long the Sawdust festive and Pageant of the Masters is running into Sept. Newport is good for bike riding on PCH, 2 Piers, Balboa Island and Ferrry. They are really close together so you could see both!

Turo is an app...similar to air bnb or vrbo but for cars

44th and River should be just a couple blocks to beach. You should be fine with traffic because it's at the end of the peninsula close to PCH. Then you would maybe bike the alley to the boardwalk (on 38th?! I should know that haha) and you'll be on your way to Newport Pier in no time. Balboa Pier and the Fun zone are just a ways past that. Parking is always a challenge but with patience you should find a spot. Visiting LA, while close, you'll need to avoid rush hour times, but usually its more clear in am going to LA and evening returning from LA than vice versa. Good luck and have fun!

Book the ticket online to get the cheapest prices and try to avoid weekends .. i guess 2 days at least to visit the whole park if u r quick , but if u want to take mote time and do the rides more than one time then u will need more time .

then Las Vegas is a must , i guess u rent a car and don't miss SanDiego , Monterey .. u can also go to Hollywood , Sea world & 6 flags if u want to have some fun .

Recommend contacting a bicycle rental shop- they would know.

I recommend to go to Laguna Beach and to stay at the Marriott's Newport Coast Villas the location is great and you can rent it from owner, surfing and walking and getting around very easy to everything
