I feel your pain - my bags missed a connection in Madrid on the way to Ecuador, and the next day we were heading out at dawn on a tiny plane then boat then trek to a jungle lodge departing well before the next daily flight would arrive. In our case there was no chance of a resolution and I was just lucky that the dawn flight couldn't land at the destination airport due to weather so had to abort and return to Quito, telling us we'd try again in the afternoon, so I had time to go shopping! No real lessons learned to be of any help to you but you have my sympathies.
Will you be calling into any major ports in the next couple of days? Perhaps the gold line could arrange to have your bags delivered to the port for you to collect?
Other than that I have heard stories on here of people who have had to buy replacement ski gear in similar circumstances and have managed to get that reimbursed even though of course that was very expensive, so cruise wear should surely be the same principle.
