My teens were not bored at all! I have two teenagers(boy and girl) and we brought along two of their cousins(another boy and girl). Everyone has a different personality; some are more outgoing than the others and I felt like everyone found their niche.
The four of them did some of the scheduled teen game nights and scavenger hunts, but then also explored the area on their own. My son and nephew really enjoyed the ukulele class(sign up early because spots fill up fast) and my daughter and niece liked getting snacks and taking pictures with the characters. Everyone loved the pool area.
My daughter always says that the trip with her cousin was the most fun trip she has ever had, and my son keeps asking to go back so I think your teens will love it!
