Los Angeles, Las Vegas parent-child travel first stop

In August, I took Guoguo to the United States for a 2-week summer camp, and I have organized a non-tiring version of Los Angeles and Las Vegas child-walking strategy. ✈️Tickets: about 10k per person 🏨Accommodation: Hollywood 3-4 days, then near Disney for 3 days, then go to San Diego and Las Vegas. You can stay in a hotel or a homestay, and the homestay has a higher cost performance. If you don't move, they are all far away, Los Angeles is always congested. Day1 Hollywood Walk of Fame, Wax Museum, Sign walk, Theater walk, Warner brother studio (70 dollars need to be booked in advance) Day 2 Getty Center free (🅿️20 dollars, after 3:00pm 15 dollars) Santa Monica Pier(🅿️15 dollars) End of Route 66 photo + amusement park (20/dollar play at will) If time permits, you can also bring a picnic mat to play by the sea. Day3 Universal Studios (🅿️30 dollars) Beverly Hills Shopping If you are in a hurry, you must buy a fast ticket, otherwise the queue will be super long. The most distinctive feature of LA Universal is that tour, which is worth going to, and you can also walk Single Rider. Day4 California Science Center free (🅿️15 dollars) The natural museum next to it is said to be very good, but I didn't go, it charges. Observatory (🅿️ parking is a bit hard) Day5-Day6 Stay for 2-3 nights, otherwise it's too tiring Disneyland park+ Adventure Park (🅿️30 dollars/day, or do hotel hSuttle) Day7-Day8 San Diego old town+Midway Museum (🅿️ parking 20 dollars) +Legoland (🅿️ parking 30 dollars) If you want to play in the water park for a day Costco has 2-day tickets for 129 dollars/person (membership card required) Day10-Day12 Go to Las Vegas (about 5 hours by car, hybrid car half tank of gas 25 dollars), the plane is very fast. Free attractions on the avenue + watch Show at least 2 nights. Free attractions recommend Mirage Volcano Show, Bellagio Fountain Show, Silverton Mermaid Show. Choose to stay on the avenue, because parking is expensive. Free parking: Treasure island/Wynn Shows suitable for children: Blueman and Ka show, because it is very hot during the day, remember to buy tickets one day in advance. Little Guoguo watched the little blue man and loved it very much, and was very excited throughout. Day13-Day14 Grand Canyon + Antelope Valley Considering that self-driving is very tiring, I didn't go to the Grand Canyon for time reasons, but I also made a strategy. Those interested can join a one-day tour for 275 dollars/person Helicopter 🚁500 dollars/person.
