blueliner covered it in the most positive light. However, on my upcoming cruise on Princess, the TA made a mistake and sent my final payment to Princess; but it was $550 short. Princess contacted the TA and I had to pay the $550 that day or they would cancel my reservation.
I doubt that RCI would be any different. They are not in the business of lending you credit and they will want full payment when due.
