Our March '05 Zaandam cruise was fabulous. We'd had plans to go skiing, which fell through suddenly, so we went online, typed in "last minute travel", and booked 2 Verandah Suites (6212 & 6218) for our family of 5 - less than a week before sailing. My in-laws decided it sounded pleasant, and came along too. We're in our mid 30s, with 3 kids ages 8-12. My wife and I played with the kids, relaxed, and had twosome dates. The kids played, rested, watched movies, swam, and enjoyed ClubHAL. My college-professor father in-law graded papers and swam with the kids, while my mother in-law, read, took cooking classes with my wife, and enjoyed the beaches. Our week on Zaandam provided a perfect mix of different activities for all of us to do together and in various pairings.
The Ship & crowd. Zaandam is big enough to provide plenty of space and things to do and to handle the ocean well. It's clean and classy, but not stuffy. A previous cruise on RCCL was more like a week at a giant indoor outlet mall during the Thanksgiving sales (crowds, lines, noise, commotion - this is fun?), while Zaandam offered a comfortable, refined atmosphere - without the chaos. Our fellow passengers were pleasant to be around, with the average age "energetic 50s". Furthermore, they were gracious to our children, often lending a hand if one of the kids needed it.
Cabins. Our 2 suites were simply lovely. Quiet, comfortable, perfect temp control, lots of storage. Fresh flowers were a welcome touch. Flat screen TV and DVD/CD player were a real plus, especially with the kids (satellite TV with cartoon network; plus 945 DVDs in the library). I appreciated the comfort of the bed - think Westin or Ritz Carlton. Every evening the sofa in the kids' room was converted to a bed, which my daughter thought was cozy. The verandahs were really pleasant; clean, quiet, not windy - definitely worth the extra money. Our room steward, Laode, was incredible - always greeting us with a warm smile, keeping our rooms neat, replenishing our fruit, and making a special point to fuss over the kids. Requests were never an inconvenience, and his follow through was 100%. I'm convinced he was genuinely glad to have us as his guests.
