There is no fee when there is not an event going on
No fee, except special events. Take all the photos you want. Have fun!
Yes you can take pictures, individually or in group. There are no fees to enter, except if there are events happening the day you go. For example, during Christmas, they have events that will have a charge/fee to enter the garden and stroll around.
Yes you can i take photos all the time when i go..
No reason you can't take group pictures that I'm aware of.
