We are going on the Disney Magic 5 day cruise out of Galveston in March. We have 3 kiddos, ages 3, 5 and 8. A couple of questions... 1. I did not see anywhere while checking in online to sign up for kiddos activities ahead of time. Is there a place to reserve specific activities for kiddos onboard? If so, what is best? 2. My daughter really wants to go on a Dolphin excursion. She is 8 and wants to at least pet the dolphins, but would really like to swim with them. The boys (ages 3 and 5) say they want to, but not sure they actually will. Trying to decide best alternative. I know the youngest is too young to actually swim and if we picked that excursion some of us would be "observers" and while she and DH swam with the dolphins. The other alternative is to do the Discovery excursion where we can all pet the dolphins, but no swimming. SUGGESTIONS?? ADVICE??? 3. Lastly, any wonderful tips about Disney Magic that I just have to know? THanks!!
