On the Dawn in the Fall of 2009, portraits were taken about 5 nights of the 7 night trip. It is free to have your picture taken; should you decide to select one, they cost us $25 each, or buy 3 (for $75) and get a fourth for free.
My girlfriend and I had many portraits taken, we loved the experience, and from the looks of it, many of the other passengers (particularly men) enjoyed it too!
