So I'm not a guest time cruiser but a friend asked me to go in a cruise with her, her daughter and some of the daughters friends (and asked if of help find a good cruise for them). I'm in my 40's, no kids, never traveled with them so I need advice on which cruise line (Carnival or Royal Caribbean) would be good for teens? They're around 17 so nothing to juvenile. I was thinking Carnival as it seems more "fun" but again, being older, I'm more there for the higher end wine/food/show experiences so what do I know! It'll be mid March (spring break) out of either Tampa or Orlando (we live in Florida). None of the kids have done a cruise before, and I think my friend may have only done one, so I'm the designated "expert". Any advice on a good cruise line for older teens?
