You are always welcome to take pictures with your own camera. But if you're taking your kid for the first time I would recommend paying for Disney maxpass for atleast 1 day of your trip. That gives you access to all pictures taken by disneyland photographers. Plus you get to pick fast passes throughout the day to skip the long ride lines.
You can take pix
no it's free just need to find them
