Got curious...so I asked....Reviews are "verified" when booked thru certain cruise agencies affiliated with this site. Upon return, cruisers get an email from them so they can post a "verified" review, based on their booking #. The implication is that unless its verified, anyone can log in HERE, and post a review of a cruise they never actually sailed on, let alone even booked. Which again is why, after all these years in here, I look for reviews by NICs I've learned to trust, verified or not. I usually do read several from anyone who cares enough to bang the keys, for ships and upcoming cruises I'm interested in or booked on. Then it becomes just a question of how accurate my guts tell me they are.
We've had this discussion....sometimes some of the reviews are so "far out" you wonder if they cruised on the same ship. Beauty is in the eye of the beholder I guess.
