I dislike the process of putting down a deposit only to find out that vacation protection must be purchased at that time. HAL gets all worried about non refundable deposits that they want vac protection purchased at the time of deposit.
I found out the hard way that a few months later if changing ships, NOT allowed to buy vacation protection. I mean it is an ADD on and should not be prohibited later.
Also HAL when making changes to a reservation, actually assigns a new Number and then one can get catch in a trap of newer promos or rules that changes the value of initial reservation.
HAL really is overly annoying with their promos and use the word promo to backup any sneaky crappy thing they try to down the road.
