Comparing prices doesn't always mean you'll get the same service. Be sure you're comparing apples-to-apples. Remember the old adage of you get what you pay for. Booking with a large singles group (200+) means better upgraded cabins, as well as many extra amenities. SinglesCruise.com offers 3 complimentary cocktail parties, singles activities/events, souvenir gifts, etc. These activities are not offered/open to the public but exclusive to the group. Booking with a "true" singles group can be lots of fun.
