Hi, I know there is free internet in the lobby, but has anyone added on a small data package (120MB) for $30 through At&T? If so, did it work ok at the hotel? I am contemplating adding it to my phone, to use throughout the hotel and Ocho Rios to check email, internet, etc. but want to make sure it works. Last winter I was in the Bahamas and it didn't work too well.
