I sailed on the m/s Maasdam on the 7/30/00 sailing from Stockholm and while HAL indicated that Mariner members would be given priority boarding, I did not find that to be the case. Boarding was easier and smoother for my first HAL cruise(out of Montreal aboard the m/s Veendam in 1998). If Mariner members were given prority boarding, I did not know of it, and did not see any indications to that effect at the pier.
