I attended my EE session almost two years ago in 2005. It's still fresh in my memory. I have to say it's probably one of the best things we've done as a couple prior to marriage. All that 'paktor-ing' is good, but to actually sit down and collect your thoughts properly and write things down, on a range of very important issues really brings things into perspective. None of the issues was new to us, but it took on such a different light when actually reading my then-FH's thoughts.
I can see why it can seem quite daunting for non-Catholics, and infant baptism was probably the thorniest issue among the inter-faith couples in our group, but really, the atmosphere was really open, and the facilitators were very hospitable, no question being taken lightly or dismissed. It certainly wasn't a weekend used to 'convert', but to prepare the couples for marriage, and to explain the Catholic position on various issues (afterall, at least 50% of the couple was Catholic!). Well recommended.
