Question About Game Updates... Options

[gfhmkm]

Hello,
I am taking my 360 to with me on a trip for the weekend and there will not be any internet connection. When I am at home I often get a message that says "this game requires an update before you can play". I assume that if I don't have an internet connection it won't know that there is an update for the game thus I will be able to play without any problems. I just don't want to get stuck with a system thinking it needs an update but doesn't have the ability to do the update.

Is my assumption correct?
