If you booked onboard and already named Dreams Unlimited Travel as your TA and move that booking to the PCC 4.0 sailing you can keep all of the perks and benefits you received from DCL for rebooking onboard as well as the current, full shipboard credit from Dreams Unlimited Travel....
The staterooms we have held under group space are priced as seen on the linked page provided. They are eligible for the full, current SBC from Dreams Unlimited Travel but not any additonal offers from Disney Cruise Line (Disney Visa, rebooking credits, etc)
Now I'm confused! Are you saying that if I book one of the "A" cabins DU has on hold - that can't be combined with the onboard booking discount and OBC? Any other cabin category, or an A cabin booked at DCL's current price, does get the discount and OBC?
