correct, and neither do the Edge kids, since neither is a lock-down like Oceanears Club/Lab. Edge also has activities that have them roam the ship, and Edge goes into Vibe some times for "takeovers" or "Smoothie Hour". I liken them to Middle School and High School type situations - many Middle School age kids can still be silly and act like little kids or be more mature and act like high schoolers - YMMV. I was not comfortable with my 10 year old being able to hang with her 8th grade sister in Edge in March, as there can be some different conversations and attitudes with middle schoolers that I didn't feel she needed to be exposed to, and i was not comfortable with the 8th grader moving up to Vibe to hang with high schoolers for the same reasons, but that is me. 8th grade girls and high school junior/seniors can be at very different maturity levels and that is what you can get with the age spread they have on
DCL. Just be aware if you are going to age up your kids what might be awaiting them, other than being able to hang with their siblings/cousins/etc.
