Carnival Cruise Line will implement dynamic pricing for drink packages and WiFi on Dec. 1.
Prices will depend on the season and itinerary, Carnival said.
A Carnival spokesperson said the change "creates more flexibility and accounts for seasonality."
Currently, Carnival drink and WiFi packages prices are based on a standardized daily rate. The "Cheers!" drink package, which includes up to 15 alcoholic beverages per day, is $69.95 per day if purchased in advance and $5 more per day if purchased onboard.
