D23 Gold vs Silver

I apologize if this has already been asked.

I'm a charter member and my membership expires at the end of October so I started looking at the two different tiers of membership. Am I correct in seeing that the *only* difference between the two is the magazine subscription? I enjoy the magazines when the arrive but my mom is a member and she gets the magazines so I always end up reading hers anyway since she tends to get hers first. Regardless, if that is the only difference, then I will go with the silver membership. I could really use that $40 savings. I don't want to lose my charter member status or access to events though, my mom and I are planning to attend the Destination D event next month as well as the Expo in 2011.

Does anyone have any info about the different tiers? Thanks so much!
