Slightly off-topic, but is there a way of looking at Disney gift card history, beyond 15 transactions? I transfer value of new cards to the old one, so there is a long history of credits and debits.
The last time I stayed at a Disney resort, I paid off my resort balance with the gift card, before checking out. That left a zero balance on the gift card. The CM started to throw out the card, and I had to abruptly stop her. I knew there was a large credit pending, due to cancellation of a resort reservation paid with the gift card. Without that physical gift card, there would have been a sizable hassle to have that credit re-issued and transferred to a new card.
A few days after arriving back home, that refund was showing as a credit on my gift card.
