It is not as good a value as it is in disney's even if it's cheaper.
There are less photographers
But it's still a pretty good value.
We did the 5 days package when it was offered a few years ago, but since then we have the passholder package, so I can't really comment on the value on a 1 or 3 days package.
But the way I see it, without the photo package, there is always a time when one would like to get a picture, and give up because photos in theme parks are so expensive. Buying the package in advance takes away that consideration. See a photographer, get your photo taken. Ride a ride, know you'll get the picture.
and in that light, it's well worth it.
