Funny, I was responding about B&K too when the phone rang and I exited out of the answer...
One thing I see is your Question about the $1000 free air on top of the Two for One. It's usually one or the other - that's why your fare seems so low. Editing to add that the best way to compare pricing is to figure out the fares with air/without air and come out with a daily rate including port taxes and other charges. Then you have a real rate to compare.
