Yeah, as the others said the best option is the computer room. Though I've never seen it closed, and hopefully they wont close it this year. I mean I don't use it much but occasionally I'll just on to check dvd prices if I see something in the DR. Since I plan on doing that beforehand this year, guess it wouldn't be a big deal exactly.
But yeah I really doubt they'll ever give free wifi, definitely would cut into their profits. Minor curiosity, wonder how much they make off charging for internet during NDK/Starfest weekends? Part of me wants to believe it's a lot but I don't know...oh well. Anyway yeah OP your best bet is to use the computer room, phone tether app, or check the local businesses for wifi hotspots. Hey does anyone know if Wendy's has free wifi? I know some fast food places do, that may be an option.
