11 Great Cruise Deals for 2018 Under $100

Is a budget-friendly cruise on your 2018 agenda? Despite the hurricanes that hit some areas this past year, it's "full steam ahead" for the 2018 season. Sailing during the so-called "shoulder months" can save a lot of cash. That means avoiding the Caribbean from June through August, when there will be a significant spike in prices due to summer break, according to experts at Cruiseline. Think May and September for destinations such as Alaska, and April, May, and October for Europe. Folks who aren't picky about the ports or ship can enjoy big savings. Cheapism asked Cruiseline and Expedia CruiseShipCenters to identify the top cruises of 2018 that cost less than $100 per night. (Note: Prices and availability are subject to change.)
