Last year, we pre-ordered the 10 credits credit package as you couldn't get less than 20 credits on board. I don't see it as an option, so I am wondering how Shutters works for photos. We are not going to spend hundreds of dollars are photos, so the CD is not ideal for us. We just want a few family formal pictures, and a few character picture (maybe 4 - 5 pictures total). How does Shutters work now? Pricing and options? This a 7 day Fantasy cruise in January.
