Westerdam, the third of four ships in Holland America’s Vista class, may be two decades old, but refurbishments have kept this 1,916-guest ship up-to-date and even added an energy that wasn't there when the vessel was new. Today, Westerdam pulses with music thanks to evening venues Billboard Onboard and Rolling Stone Lounge and with competitive spirit courtesy of complimentary pickleball lessons and tournaments on the sports court. Of course, you can also find the quieter activities — from bingo to craft classes — for which the line is renowned.
