I priced around before going to AAA. EVERYONE had the same price including online and direct . However Holland America is a AAA prefered supplier, which means there could be additional on board credits, more discounts and prefered upgrade opportunities on certain sailings. . They have their own designated line into HAL which means less of a wait time in the call center q to get the info you need and want!
I'm not saying they are the end all be all, You should always do your homework and never assume one distribution is better than another. This poster wanted answers quick so I gave a solution that work perfect for me.
