Registration code for sims 2 bon voyage PC game

Registration CodeIn your PC 'Sims: Bon Voyage' Game Case, there should be a little booklet, like the ones that come with most games. (by most I mean Wii, DS, X-Box, all of those systems, all of their games) On the back of it, at the top there should be a code; if I know what a registration code is, then that's it.
Note: if you got it from a garage sale, it might not have the booklet; sorry!
Hope this helps!
