I just got off the Monarch last weekend. I did a onboard deposit of $100 for a future cruise, yet to be determined. They said it was good for a lifetime. They also gave me 2 others vouchers, to give to 2 different other parties. The vouchers state "with our new onboard booking program you can secure the great offer of up to $200 per stateroom onboard credit. Simply select the same ship and sailing date as the guest who supplied the certificate." ..."within 30 days and mention your certificate number or call..." It does say you have to mail the original certificate to RCCL. "Allow up to 5 business days for onboard credit to be applied to booking. The booking will be crossed referenced with the master booking. Guest forfeits the onboard credit if at any time the master booking cancels." Is this something new? The last time I cruised, Freedom 06, they didn't have the future cruise deposit. I'm glad they did this. I think it's kinda fun.
