Yes I recommend the photo pass but if you decide to do this then decide before you go and not half way through as it's the same price no matter how many photos you get (my point the earlier you decide the more photos you get-as soon as you see a photographer grab a pic)
I took my big camera and I didn't regret it . I didn't want to spend all that money going and end up with poor photos. My point and shoot isn't very reliable on getting good photos) I didn't have an iPhone when we went last August. I didn't find that my big camera caused much hassle. But then again it's my main camera and it usually goes everywhere I go.
