I’ve bought a bunch of discounted Disney cards that I want to use to pay for meals, etc. during our trip. I’d like to use my MB to charge to our room, and then use the gift cards to pay off the balance at the resort. I tried this on my last trip and messed up the timing, such that when I went by the front desk to use my gift card, they’d already posted my charges to my credit card on file. How/when do I need to go by the front desk with my gift cards to avoid this on my next trip? Thanks!
