While it may seem crazy for Carnival to provide discount rates for group travel, it actually provides the cruise line with a number of benefits. When the price is lower, more people will be tempted to join the group, putting more money in Carnival's coffers. Further, the last thing Carnival wants is for its staterooms to be empty during a voyage.
Carnival defines a group as occupying at least 8 double rooms, meaning 16 people. According to Christine W. Koubek, writing for Budget Travel.com, the person who organizes the tour may qualify for a deeper discount than everyone else, sometimes even cruising for free.
Cruising as a group also qualifies for special bonuses, which reduce the real cost of your cruise. According to the Carnival web site, you could even host a private cocktail party on the ship or receive free champagne and chocolates.
In order to get the best possible price for your group, you should book your staterooms as soon as possible. While it may seem difficult to get so many people together to plan for so far in the future, that's just the way it works. Booking very early also allows you more choice in terms of the location of your rooms. Not only will your group be closer together, but you will also get the staterooms with windows, if you want them.
In order to get a cheaper Carnival cruise as a result of group travel, the company suggests you contact one of its representatives. This person will give you information tailored to your group.
