I have now been to the Getty Center 3 times once with my ex (not my ex at the time) once alone and once with my stepdaughter who is 10 (the most recent trip). The Getty does not disappoint no matter who you hang out with there. There are so many things to see whether it is canvas art or textiles, sketch work, gardens, sculpture. The only thing I really do not like about the center is the food court. The food is simply sub par (think school cafeteria) and very expensive.
However if you bring a sandwich and drinks you can eat well for much less!
It is peaceful and beautiful all around you're high in the hills but no worry the tram brings you up there. The parking is easy underneath however the outside areas of the Getty are super hot during the summer months. Still overall it is a wonderful experience for most ages.
