What is the best cruise line for our family?

I am a teen and i would deffinetly choose carnval i yhave been on six cruises and by far carnival was the most fun it was alo of ffun there was many activities. Carnival also has very good deals.THey have many pools,and geat shows .I would scratch Norweiga off your list it is to expensive . I wouldnt cosider holland american or norweigan they are usually more for the older people. BUTi would say the bet option is Carnival and the second best is Royal Carribean.Have fun.
