We stayed at the CR for 12 days this last Sept and really liked it. We were in the NGW, and even though it wasn't the tower it was really awesome. We were right on the bay, ground floor and could see the EWP from our bed! It was so convenient to be able to walk/monorail to MK and monorail to Epcot. We had a great time at Chef Mickey's. The food court could be better, but oh well. The quiet pool that's right out on the lake is neat, and the water slide in the main pool is fun.
One of our favorite things was renting watermice from the CR marina--IMHO your teens will love this. You are able to ride on both Bay Lake and Seven Seas Lagoon. DH is just an overgrown teenager, and he is STILL talking about those watermice 3 months later.
Since your kids are teens, maybe you and your spouse can slip over to the Outer Rim Lounge, get a drink, and curl up on one of the couches that are in front of the windows that face Bay Lake and watch the EWP.
As silly as it sounds, DH and I
loved having the monorail literally in our hotel. I can't explain it--it was just so cool to see that monorail gliding down the track towards you.
I have also heard that the CR has the best arcade on property, so if your kids are into video games (do they make teens that aren't

), that will be a bonus, too.
Just as an added endorsement--we have 2 more trips scheduled this year--both times staying at the CR.
