For me info's are useless.
Can't be really objective on the value of these items but if one have a better value than the others it will certainly be the dreamcruise.info.
Good luck anyway
NewYork.info sold for over 28,000 recently. Europeans seem to really like the info ext, and seems to be becoming more popular here also. You wont retire reselling this type names. But you can still make money with them.
You have chosen a popular subject with cruises (and with a marine background I am obviously biased!) but marine companies have generally not yet woken up (IMHO) to the value / importance of domain names yet, and pushing dot info's may be a bit of an uphill struggle.
These two links may give you some food for thought and one or two potential endusers:
Do the numbers, get the emails out and you might be surprised what nibbles you get back but don't expect vast values for each name - most of my end user sales are currently in the $200-500 range and that is usually for a dot com.
