Finding a computer on-property

One morning during our trip I’m going to need to make a time-sensitive school registration for my DD back home. I’m not certain how well it will work on a mobile device either. This should take maybe 5 minutes tops when the system opens, but I don’t want to have to haul my laptop to WDW and back just for one 5-minute task.

How difficult would it be to find a computer on property with internet access I can use briefly? Any thoughts on options I might have?

Several of the hotels have business centers, with desktops available…

Not sure where you’re staying, but I know that at least several of the DVC resorts (if not all of them) have a small room with a PC and printer, which guests can use to print out boarding passes etc. It’s free to use, you just need to ask the front desk as they keep the rooms locked.
