As long as you have a phone with internet service, that would be your quickest and cheapest option --
POP does not have any wireless -- it's just cable connection -- in fact, none of the parks have wifi either -- so you either need to have a computer that has its own data built in that connects to a phone service, a portable router, or a phone/iPad that is 3G enabled for data....
Just as a heads up -- NOT ALL AREAS at WDW and the resorts have good phone data services for your phones/ipads either -- it depends on where you are in your room -- you may need to walk around a bit to find good service. FOr example, there is virtually no 3G or EDGE signal around the American Pavilion in Epcot -- a place you would thing would have good phone signals considering it's a major dining/hanging out area....but no. Similarly, there is almost no cell/data service for ATT in the southern portion of Riverside and the northern buildings of French Quarter....
Good luck.
