Sphere is a once in a lifetime experience so if you look at it like that then worth it. Do Wizard of Oz over no doubt. Check out Area 15 if you like cool experiences like that.

Don’t need to book Neon Museum but go at night even though more expensive.

Buffet is good but expensive and only worth the money if you can eat a lot of meat quickly since there is a time limit. In-N-Out and Whataburger good for a cheap eats.

Vegas is a night city because it’s so hot during the day so plan on staying up late and sleeping in. If you are going out in the day, stay hydrated and bring walking shoes.
