I'm a WDW and DL veteran but have only been on one cruise in my life back in 1984 and it was not with Disney. Am just starting to think about taking a cruise with my husband. We have no two kids and live in San Diego. Want to keep it reasonable as to price, but at same time, want to have a nice room. Most important is for it to be quiet and as little motion as possible. Any suggestions as to which deck and type of stateroom? I'm finding this info confusing to understand. Also, I believe we would keep it to a West Coast sailing.
