Market Watch says you can cruise on Royal Caribbean for $32 a night.
Yes, it may be an interior cabin. And yes, you run the risk of catching norovirus like a record number of passenger did recently on Royal Caribbean’s Explorer of the Seas. But what the heck, its cheaper than staying at a Motel 6 which starts at $39.99.
Market Watch says that the low price may be a result of Royal Caribbean’s recent woes with the Explorer. When disaster strikes or a "cruise for hell" affecting thousands of people hits the press, cruise lines often drop their fares. Of course, the cruise line is also trying to prime the pump for wave season.
An article in Reuters, As Outbreaks Hit Cruises, Are Deals Worth Risking Illness?, explains that "potential travelers need to weigh the odds they’ll get sick against the amount of money they might save now, and see what they can stomach."
