If Princess had announced that wef Aug 01 that all new bookings would incur these additional fees, then I believe there would have been far fewer "comments".
But they didn't ... they are charging a group of passengers for services that, at the time of booking, were included....which frankly stinks.
As it stands (at the moment....) our next cruise with Princess is unaffected (unless we have 3 or more Alfredo pizzas)....we like Princess but it appears they cannot be trusted and that will definitely be a major factor when we book our next cruise.
