I see comments about lack of internet access, having to pay etc... what about internet access from iphones - does that not exist/work at WDW resort or parks? I am not bringing a laptop as I figured my iphone would be fine with the unlimited internet access. Will it not work... please help me understand. My first trip is in 14 days - Mar 15-20, 2011 for my grandson's 5th birthday, staying at AllStar Sports. Thanks!
