We sailed on the Eurodam from 10/29 to 11/5 2011. We are both under 30 and took this trip to celebrate our fifth anniversary. We were told going in that Holland America's clientele is on the older side, and while this is true, it didn't affect our enjoyment.
EMBARKATION: The only accurate words are "quick" and "painless". We were on the ship in plenty of time to eat lunch in the dining room. Our bags were in our room when we first got there, and our wine/soda was brought shortly thereafter. Big props to HAL for letting guests bring cases wine on board. We saved tons of money by going this route.
CABIN: We were in inside stateroom I-8045. When we booked with HAL, were told that the cabin was one of the largest inside staterooms on the ship, around 284 sq ft. It was closer to 210 sq ft. However, it was very spacious with a table & chair and a corner couch. We were blown away by the amount of storage space. There were three full wardrobes that could be customized with foldable shelves. There were also two drawers under the bed as well as drawers in the nightstands and make -up desk. The bed was incredibly comfortable. The bathroom wasn't huge, but there was plenty of counter space and shelving.
Spacious, one of the largest inside staterooms (roughly 210 sq ft). Ample storage. Slight noise from Lido hot tub during the day. Conveniently located. Comfy bed.
