From the HAL blog: caution - older post - hope phone number is still good.   "We do our best to keep our guests with dietary needs in mind when planning our menus. Traveling should be an enjoyable way to experience the world, and we encourage our guests to feel empowered to have a carefree vacation with Holland America Line! If you have special dietary needs that require assistance, please contact Ship Services at least three weeks prior to your departure: 1–800–541–1576."
