Yes, you should be able to order them. I'm not sure if it's because you just booked today though. Call Disney for assistance. There are some things Disney isn't able to help you with directly if you booked through a third party, however. Disney may tell you to contact Orbitz, and Orbitz would then contact Disney with the issue. I always try Disney direct first. I've booked Disney hotels through Orbitz twice before with no issues.
