They have a couple different incentives going on right now for add-ons at BLT. The first is $8.00 per point off the $112 per point cost, plus a free cruise (the length of the cruise depends on the number of points you purchase).
The second is $8.00 off per point up to 100 points; $14.00 off per point for 100-124 points; and $16.00 off 125 points or more.
We opted for the second offer to save a little more per point. Plus, we're not really cruise people, so that made the decision a little easier! :D
