I'd say it's definitely worth the money! I am an older teen (19), and last trip I ate here with my siblings (16 and 14) and parents. I knew that the meal was expensive, but it was absolutely the best meal of the trip. I'm going back with my boyfriend next week and absoultely HAD to make an ADR so he can experience it, too. And last time I was there for Wishes, a couple of trips ago, the lights were dimmed and it was awesome.
If your two teens can eat like my siblings and I (and all the rest of the teens I know!), you will definitely get your money's worth!! Have fun!
