Hi there, Weiren!
Welcome to planDisney! Thanks for coming by with your question. I see that you will be visiting the Disneyland Resort during the Holiday Season! That is arguably one of the most beautiful times at the Resort and Cast Members really go all out to celebrate the Holidays! It's one of my favorite times to visit!
I'm sorry you're having trouble adding your Singapore based VISA debit card as a payment method. Are you attempting to do so within the
Disneyland Mobile App? If you go to My Profile and click on Payment Method, there is an option to Add a Payment Method. Be sure to use the pull-down menu and select "Singapore" as your Billing Address Country. This will change ZIP code to Postal Code and State to State/Territory. Once this form is properly filled, I would hope that it would save your card successfully as a form of payment.
If this does not work for you, I would recommend contacting a Cast Member through the
phone directory for further assistance. You could even email them if you would prefer. Singapore also seems to have its own Disney help site where you can
request support.
I hope that you are able to resolve your issue before your visit, Weiren. You're going to love seeing the decorations throughout the Disneyland Resort. Even the Disneyland Resort Hotels are decked out! I especially love the ambiance of the Grand Lobby in
Disney's Grand Californian Hotel & Spa at that time of year, so drop by and grab a cup of hot chocolate by the fire!
If there is anything else we can do for you, please stop by again anytime, Weiren!
Have a Magical Day!
