Wife and I

I have always booked my cruise offers via the phone from the offers that were snail mailed to me. For the first time I just went on the casino royal rewards website to view some other offers. The descriptions are vague and I would like some further info on the offers. I am worried that once I hit the "redeem" button for further info that I may have started the redemption process and then I could not back out without losing the offer. Is there a better place to view these offers, or can I back out after I hit the redeem button to review?
