Holland America Line’s Westerdam may be more than 10 years old, but refurbishments have kept this 1,916-passenger ship up-to-date and even added an energy that wasn't there when the vessel was new. Today, the ship pulses with music straight from B.B. King’s Memphis nightspot, both mixology and cooking classes are on offer, and there's even a pub crawl. Of course, you can also find the quieter activities — from bingo to craft classes — for which the line is renowned.
