I am looking at a sailing in August that has current pricing that is appealing to me, so I want to lock it in now, in case prices go up. However, I am going on the Enchanted Princess in May and planning to play a decent amount in the casino. Final payment for the August cruise wouldn't be due until just after I return from my May sailing. If I were to be offered some sort of casino comp or discount based on my gambling on the May sailing, would I be able to cancel and rebook the August cruise using that promotion or does Princess have a policy against that?
