With the popularity of all inclusive resorts over the last few years, cruise providers have started to offer their own all inclusive packages.  The difference between an all inclusive cruise and a regular cruise is typically the tips and alcohol are included in the all inclusive version. 

If you have ever taken a cruise, you know that tips and alcohol can add up to almost half or more of the cost of a cruise, depending on how much you drink.  With the advent of the all inclusive cruise, this added expense is paid upfront, so you don't need to worry about paying at the end of the cruise.
