This was a slight concern of mine as we have selected the 'Love Package' which only includes 24 pictures and they upgrade on the package for another 12 pictures is $200 - this is extremely expensive as in England you would get unlimited for around $500.
You might be able to negotiate this to get all the pictures since you are not a large group. The standard package that they offer regular resort guests is 30 mins (although we went for over 45 mins) and is $500 for unlimited pictures, which was about 100+ photos for us. Also, there are photographers walking around the resort all the time that will take random pictures of you. We got a couple with a cute monkey that sat on my fiance's head and ate a cucumber. All those are included too. The extra album was $50 and we really liked it.
