My family is looking at cruises for over New Years next year and it seems that the only ones that will fit in are schedule are Carnival cruises. My family has been on 8 Royal Cruises and is going on our maybe 9th and 10th this summer. My parents are a little skeptical about trying Carnival. I, on the other hand, am all for it cause I love trying new things. What are the main differences between Royal and Carnival i.e. the atmosphere and such.
