Thanks Thom - your reply is helpful.
Do you think you get extra perks (eg. OBC or upgrades) from your PVP that you might not get from a TA.
To me the advantage of a TA is that they can help you accross all cruise lines. My TA is wonderfully helpful, but her agency does not give a lot in the way of OBC. I'm wondering if I should work with a PVP to get OBC or other perks and then transfer to my TA. [I know I can, but I'm wondering if I should]. And I wonder if a PVP would be less likely to give perks or even work with me, if I routinely transfer to a TA after booking.
