Im going on a vacation (today actually!) were going to disney and I know they only have ethernet internet from last year. last year I had my macbook but it has since died. now all I have is an ipad 2 and iphone 4. so im considering buying an airport express for the hotel my worry is will it need to be setup? I dont have a laptop to set it up with so im wondering if the purchase will be for nothing........Anyone know?
