Sorry about the wait!

I'll try my best to tackle some of your unanswered questions:
We booked the "teens only" excursion at
Castaway Cay for snorkeling, kayaking and biking. It says it is 4 to 4.5 hrs long. Any comments on this? How far out do they kayak? My son is experienced in kayaking in rivers and lakes but not the ocean. It was only $35...that seems really cheap...not that im really complaining ...Im just curious. He is quite excited about this and hope it does not disappoint...
So this excursion can be REALLY REALLY exciting ...or really really... less-exciting and it almost always depends on 1) weather, and 2) the teens. The intensity and distance of all of the activities is dependent on their least-capable member of the group. The Counselors will keep encouraging the teens to see cool things and continue onward, but if one person is slowing down the group, they won't leave them behind.
9/10 times what ends up happening is mid kayak/mid biking/mid snorkel someone loses an earring, or the teens start complaining about getting sunburnt, or they all end up congregating in one area and talk for the whole time taking selfies. And they have a blast!
My DS is 10 and is an awesome sports kid. He plays up and can usually out play a 12 year old. Will there be any sports type things for him?
In the club/lab there are rarely any real sporty things for the kids to do considering our safety policy in our spaces.

(Especially considering there are 3 year olds in the area). What I would aim for are the "Out and About" themed activities or Edge events like Dodgeball in Open House on the Sports Deck.
Hi, CMontheseas!
Are there any plans on changing activities in Edge next year? And did they get Disney Infinity for that space?
Not drastically, when it comes to activities on board it usually takes a lot of complaints before our range of activities get changed. So if everyone keeps liking the Edge offerings, we might be doing them for a while! (Believe me, we really would love to change it up ourselves, but depending on the Youth Activities Manager on board at the time, we don't always have room for creativity.)
And yes, Disney Infinity has been ordered for some of the ships (hopefully to be approved soon!)
We will be cruising with my brother and his family. We will have three boys ages 13, 13, and 15. Is there any chance the 15 year old can stay in Edge, as his mother doesn't necessarily want the younger one moved up?
Unfortunately we don't allow anyone over the age of 14 in Edge during secure programming! If they really would like to spend time together, aim for the Open House times

. I would really recommend the 15 year old try Vibe out on his own however, are the boys very closely attached?
