During the DVC 10th Anniversary Cruise last year my family was "selected" for a photo shoot while we were waiting to embark. The experience had it positives and negatives. The shoot was scheduled for the Nassau day and required about 4 hours of our time (which was probably 3 hours too many for our 6 and 3 year-olds!). There was a lot of changing of shirts (wrong colors, too tight, too loose, etc. etc.) and we ended up getting a few "gifts" - t-shirts, hats, and nice thank-you note.
We got a private tour in Nassau and there was Tourist officials coordinating the whole thing. They actually had to stop traffic while our horse-drawn carriage went down the streets so they could get the "right" picture. The residents/drivers didn't seem too thrilled! For us, it got a bit old pretty quick, but we did get a free tour of Nassau and they gave us cab fare to get back.
The biggest negative - what ever happened to those pictures? It's odd not knowing where they may end up or if they were scrapped.
