Hi Maciel! Thanks so much for sharing all of your questions with the Disney Parks Moms Panel!
I just chatted with a Cast Member and they told me that while
Disney's Pop Century Resort doesn't have a business center, you can print documents at the front desk.
During your vacation, but prior to the day you have to work, you might drop by the front desk and ask them exactly what you will need in order to do this. The Cast Member I spoke with suggested sending the documents needing to be printed to your email address and then you will login to the computer at the front desk and print the documents from your email. Whatever your technology needs, I'm sure the Cast Members will accommodate you as best they can.
While I'm sad for you that you will have to work while on vacation, it speaks volumes to your work ethic and I know Walt Disney, himself, would be proud. Once you have completed your work tasks, put your laptop away and enjoy every magical moment of your
Walt Disney World Resort vacation!
