If you're going with the idea of having a quite moment of spiritual reflection at those sights you'll be disappointed. They are very crowded and touristy.
What I did was read about the sites the night before and/or when we got back to the Airbnb. This worked well for me in terms of getting that spiritual fill I was seeking.
We took our young kids with us. I want to go back with just my wife, or when my kids are a little older and can appreciate it more.
