Can I hand over all our gift cards and reward cards at the time of check in for an acct credit to avoid carrying numerous cards with them during days in the parks? So then we could just carry the kttw card and thats it. Or do you have to wait and submit them when you settle your acct at the end of the trip? Looking at $465 in GC's and reward card for our trip. Seems like alot but we all know how fast it goes when traveling with teenagers. Room, DDP and park tix all paid for. YAY! Suppose we'll use it for gratuity, tix upgrades if desired and fun stuff. I'm getting excited now!
