Agreed - if you get the book as soon as you enter the park, then you've got all day to do the activities and collect the stickers. There is a kiosk/station on the right side of the bridge going toward the tree...can't miss it unless it is extra magic hours and you're early...they might not be open quite yet. It can take a while to get them all, but our two girls managed to get the whole thing done in a day, so it is definitely possible. As I recall, there are about 30 stickers, and they are indeed spread all over the park, so if nothing else, the activity is a pretty good self-guided tour around the park. For anybody that thinks AK is a half-day park, this will cure them of that mindset for sure -- not necessarily because the activity itself takes a lot of time, but because it takes you to places that you might not have gone before, like the animal trails in Africa and Asia. Like many others, I'm sure, I had a vision of what these trails would be like without having actually gone on them, and that vision wasn't too impressive in my mind...plus, we were already walking a lot, so why would we want to walk even more? They are now some of my favorite places in the parks.
