Hola!
After reading here your post, I check my bank and ....I have the same situation with my Toy Story Hotel reservation: no charge yet! I called SD and my reservation is fine. I check my statement and there is no charge yet. I contacted the bank and at the beginning they told me there was no charge but they ask me to wait while they contacted Visa.. and the Bank Manager ( is a USA Bank) told me: YES! VISA has an approved charge from Shanghai Disneyland and when she game me the amount... BINGO... It was same amount of my reservation!.. =) So, she told me to wait, that transaction could take several days but was approved for the merchant ( This case SH), specially since is in China and its monetary regulations, but sooner or later that charge will appear in my statement, so I believe this could be the same situation for those who have this case. =) Try to contact your bank manager and check with the provider ( Visa o Master Card).
Thanks!
