We missed the Connect @ Sea desk being open by a few minutes on our first day so we were given a paper to sign up on our own. That worked fine and I had my DH who's pretty tech savvy turn off everything on my phone that could eat up data. Not sure what happened - he probably missed something - but I didn't click on anything other than the
DCL app for days on our trip since I wanted to save that 50 mb for when I really wanted to check FB or something and I went to open it up and my data had already been used up!
