This spring my family and I are going on a Carnival cruise. I've never been on a cruise before, so I don't know what to expect, but my dad told me that the teen room age bracket I would be in is from 14-17 (I'm 16). My little sister, who always wants to be around me, is 13. I was wondering if anyone knows if they're strict at all on these restrictions and if any eyebrows would be raised if she did all the 14-17 year old activities with me. 10 points to most informative answer! Thank you! 
By the way, we're going on the ship Elation from San Diego to Ensenada.
