Not sure where to post this, but here's the story: We have the dining plan. One of our ressies is for the Spirit of Aloha luau, which I had to give a credit card number for, although it is not charged because of DDP, just given to hold ressie. It is actually a debit card, and now my bank has sent me a replacement card due to a bank security issue and I can no longer use the old card. So my question is, do I need to call Disney with the new card info? I am afraid if I call they may accidentally cancel my reservation, but also worried that if I don't call with updated info that they may cancel it anyway. What do you think? Necessary to call or not? Thanks!
