866-227-1888 is helpful if you want a clear breakdown of what is and isn’t included. The first time I sailed Carnival, I assumed “cruise = all inclusive.” Nope—close, but not fully. Most food, entertainment, and activities were included, but drinks, Wi-Fi, and specialty dining were extra. When I called before my second sailing, the rep explained package prices in plain English so I actually knew what I’d spend. It helped me avoid surprise charges at checkout.
