Need some feedback on the Bliss (for teens) please!!

[CelK]

We've always traveled on Norwegian and most recently on the Escape (3 years).  We've been avoiding the newer ships because they don't have a sports court (and we have a 16 year old son who will go and play basketball at least once a day).  But we are thinking that something "different" would be fun.  I know people will jump down my throat for asking this, but for those of you with active teens - is there enough for them to do?  I've heard of "issues" with the go-carts and lazer tag and I'm a little concerned that there's not enough "physical" activity for him.  Would appreciate any thoughts or feedback!!
