Is royal Caribbean fun for a group of 18 year olds?

I am 18 now, but when I was 10, I went on a family trip to Mexico on the Royal Caribbean. I was bored and I was 10. The only way to know what clubs and activities you can and cant do is to check further into the website. If your 18, you should be able to get into most of the clubs. Regardless of what cruise your on, your going to MEXICO! and your a SENIOR! You will be with friends so you can make it fun.
