I think the question is more who you go with and what they want or need. To me it would never be worth it. But I just returned with my dd last night, and we have 366 mm pictures. Worth it to me, no. Problems with always making sure the photos were there each night. Problems with it being on just the main purchases persons magic band, so she always had to be around to get pictures. Problem finding photographers, just two in hs, one near beauty and beast and one on the Main Street walking in, Epcot and ak same just two photographers in the whole park. Many are not with charactors like, Alice, brave, Mary Poppin's had no photographer, many dining had no photographer for any pictures, a few had it just for the shot outside dining room.
Major major problems finding anyone to be able to help or fix problem. In 13 days stopping and asking at least once a day how it worked, we on the last day finally got someone who was able to tell what I few as the truth! It is not iPad comparable, so for us who use only iPads we had a problem. It was hooked up to a band who only had iPad. We had to call and go threw three people to get it on someone else who had computer and fix the problem, so in total we have spent probably 6 hours in two weeks to fix problem, and we finally downloaded them, but three files did not download so we need to call again to find out why. Now they are all on a computer we don't have full access to.
But one good thing, we did not have to lug around a 30 pound camera, and wait for dd to take pictures that she would never be in.
