I have twin boys, they were almost 17 when we went last summer. They would never dream of sleeping in! They go off on their own usually for the first part of the morning. They love the water rides and head for Splash first thing and ride a zillion times in a row.
Of course, they love to eat and have lots of snacks.
They like the big rides (but one does not like TOT) and they also are willing to give some of the smaller rides a try too. They will also meet up with us around lunch time (because we have the food money) and go see shows and things with us too.
The year before last, I couldn't get them in hardly any pictures. All I got was eye rolling

. So last summer I made up a picture scavenger hunt with prizes. The more pictures they took of each other with specific things around the park, the better the prizes got. They weren't big prizes, but most of them involved free snacks.

It worked and I got a lot more pictures of them this last summer.
PS- I just asked one of them, out of curiosity, to see what his favorite thing to do there was. He said go on rides and eat. Especially eating all different things everyday.
