I am really confused about Photopass, Photopass+ and Memory Maker. I purchased Memory Maker last year for $100 and it worked great. Got home, downloaded pics and videos and they were great. Now, it's $170. What is the difference between photopass and photopass+? It looks like photopass+ cost is $99, but we're not understanding the differences....confused. Can anyone help clear this up? We are leaving in about a week and would like to do something, just not sure which way to go.
