We are first time cruisers and heading on the Dream in a few weeks. My sister bought me 10 credits at Shutters for my birthday. Can someone explain to me what pictures Shutters takes? Is it like a Photopass? Will I be able to get pictures throughout the cruise and then choose at the end of the cruise or do they just take pictures when boarding the ship? I'm a bit clueless on this and want to plan accordingly. (And there probably is a thread somewhere about this, but the search function is disabled at this time). Thanks in advance!
