There is rarely any difference between the Adults Only and the "regular" departures. Except the Adults get to do the things that are sometimes done by the kids (like the race we did in the Olympic Stadium in Athens). The only time we had an actual difference that I'm aware of was when I did the Alaska trip, and the Guides took us on a tour of a brewery for lunch instead of the venue they take the families to. Oh, and they skip the Junior Adventurers movie nights.
