DS only went a couple times, so I hope I can shed some light for you. On the first day, he received an invitation from Ocean Quest, and it says, Ocean Quest is our newest Youth Activities space on the Disney Magic created for our guests between the ages 10-14. This is the perfect place to chill as you play video games, create arts & crafts, watch a movie on our plasma screen or navigate your way on the Disney Magic simulator. They then listed the times that Ocean Quest would be open, so its not available all hours of the day. Seems like a couple hours in the afternoon, then open again after dinner through midnight; sea days they were open a bit in the morning. For example, on Monday, our day at sea, the invitation lists the times for Monday as 9am-Noon-Open House; 3PM-7PM 10-14s only; 8:30PM-10PM Open House; and 10PM-Midnight 10-14s only. Not sure what Open House meant; open to all ages, open to parents to visit?? There are planned events for the 10-14 group listed on the invite, like a scavenger hunt, pajama movie night and pizza pool party night. He did the pizza pool party and had a great time.
So on Monday when I did Palos for brunch, and then wine tasting (which was fun, you must try it!), DS, in the 10-12 age group, did the organized activities during that time in the Stack, and an animation project in AP, because Ocean Quest wasnt open then. The Navigator that day listed separate activities for Teens, also at the Stack, during that time. My DS is very vocal if he dislikes something, but I didnt get any complaints from that day. He did visit Ocean Quest twice in the evening and did like the relaxed atmosphere.
Hope that helps!
