Hiya Tzu Yu!
Welcome to planDisney! First, I am excited that you are planning to visit the most
"The Happiest Place on Earth." Second, I am sorry that you are having trouble making your reservation!
Unfortunately, our international guests excluding those from Canada must speak to a local travel agent when purchasing a package or tickets to Disneyland Resort. I did a search myself to double-check availability and there are still rooms available for guests to stay at any of the three amazingly themed Disneyland Resorts which includes
Disney's Paradise Pier Hotel,
Disneyland Hotel, and
Disney's Grand Californian Hotel & Spa. I had a chance to stay at the Disneyland Hotel last year and it was just lovely. The rooms were large with one of the most special headboards I have ever seen. I don't want to spoil it for you but there is a button near the lamp in the middle of the room that will reveal a magical surprise. One of the best parts of this hotel is the amazing pool and food options. Tangaroa Terrace Tropical Bar & Grill is great for yummy bites and drinks after a long day in the Parks. Check out the
planDisney pocket guide for more details! Just an FYI, Disney's Paradise Pier Hotel is undergoing a
transformation as it becomes Pixar Place Hotel. It may affect some features you may have wanted to explore so make sure to speak with your travel agent. No matter what hotel you choose it will be magical and you will love the benefits which include Early Entry into the Parks and preferred access to hotel dining reservations.
I am sorry if this wasn't exactly the news that you wanted but I'm sure if you find the right travel agent they will guide you perfectly to California very soon. If you have any other questions, please feel free to let us know as we are glad to help!
Happy Planning!
