We always just plug our laptop right into the phone jack in our room. It's 75 cents per call everytime you dial in. We use the local # for AOL. If you aren't sure which #'s are local just call the GF operator and she can look it up to make sure. We accidentally used a long distance AOL # at the Poly once! YIKES!!!
In the Boardwalk Inn there is internet access right by the pay phones near the bar. You can insert cash or use a credit card. I'm sure there are probably other places besides BWI, but I don't know for sure.
Gregg, Don't know if I missed you or not, but there is also internet in the Conference section of the Contemporary. We also go to a Kinkos on Rt 535 just past Crossroads.
There are internet phones in every resort where the pay phones are. They take either a credit card or dollar bills. I know that there's also an internet phone at the Magic Kingdom where the pay phones are so I assume that all the parks have them. Might be expensive to do much surfing but I only used them for email and I didn't spend very much. Just be sure to read the instructions on the screen. It took me a little while to figure out what I was doing because I hate reading instructions.
