We did this last year and it was fun. You can get your camera cleaned, play with all the new toys, see the photo exhibits, attend workshops, and see different speakers.
Small group of us has already planned to go on Sunday so please feel free to join us.
I have put the opening and closing hours for the time. Everyone will probably want to look at the schedule of events to see what interests them most so you don't miss it. Personal experience from last year says that if you want to get your camera cleaned you want to be there when they open.
To coordinate when we get there my phone number is[masked] 34. It took only a few minutes to buy tickets last year but try to get there a bit before 10am, buy your tickets, and we can meet by the ticket counter.
