We did the Pirate Adventure with our oldest 2. The people who did the cruise were great with the kids. My son has moderate autism, so he can be a challenge, but he had a great time, and the adults leading the cruise were great. The other kids, however, were pretty terrible to my son, and it ruined my older daughter's trip. My son didn't notice, but my daughter said the other kids were screaming at him the whole time and by the end of the trip refused to sit near him. He misses a lot of social cues, and kids can be mean. So, it is what it is, an unfortunately, that's life for him a lot of the time.
We will probably do it again with the middle 2, and we'll see how it goes. The adventure itself is cute, and like I said, my son had a blast and loved his treasure.
