Actually the pictures you buy of yourselves onboard are pricey, the smaller ones are around $8.00 and go up from there. Some of the formal 8X10's can go for $22.00, so pick and choose wisely, but also remember too, when will be the next time you will be all dressed up and have pics taken, remember you don't have to buy them, so go ahead and if it doesn't interfere with what you are doing, have them taken and buy the ones you like.
Please go to the Photo Gallary daily and check the pics. Yes, they tend to be pricey, but they are usually very good. I saw some of my family (many times I did not even know these pics were taken) and figured I wait 'til the end of the cruise to get them. Well, if you do not purchase them when they are hanging in the gallery, you might not ever find them again! (At the end of the cruise they are all boxed according to the time they were taken -- but watch out! There are soooo many photos in the boxes, it is very difficult to find what you are looking for -- speaking from experience, I wish I had purchased some when they were available and right there!!) Always pose for the photographers -- there is absolutely no obligation to buy the phots, but you'll be surprised how they catch those "moments to remember..."
