People take photos there for all kinds of events. If you are not disruptive, they generally permit you to take photos. Just be mindful and respectful of others :-)
We visited a few months ago and took many dozens of photos. Some turned out really well. Please feel free to look at mine & like them!
I took some pictures of my great niece there. I went on a week day when it was quieter. I didn't have any problems.
The first reply is dead on. Also, during their special days, it can be more difficult because of crowds.
