Does anyone know of a way to get a refund (credit) for a rate decrease. I booked our cruise in Oct. and paid 719.00 per person for interior, just checked and the rate has dropped to 629.00 per person. Thats 180.00 per room for 2 rooms........ ughhh I called my carnival planner and he said couldn't do anything. Is there something I could do to get the lower price?
