Cruise line help? Please?

For my 16 bday next year im going with my friends on a cruise. I went on the disney cruise three years back and loved it but now idk. My mom wants me to go on that cruise with my friends bcuz of how impressed she was with it (she will chaperone so i want her to have a good time too). I dont want disney to feel too childish. I feel like the teen club is a lot of sitting around playing videogames. Royal caribbean was an option because of how many activities they have but i dont think my mom will be happy on it. Plus my cousin said when she went, the activities wete really crowded and everything. Help!!! I dont mind disney but i dont want it to be too childish. What do i do?
