I haven't been to this specific offering, but I've been to two or three others with the same format, similar price and duration, also at the local community college. I found all of them useful. No earth-shattering revelations as far as my financial situation, but more of an affirmation that I've got the basics right. All of them offered a no-charge consultation with the presenter at his company, but it was a soft-sell, in fact, not much of a sell at all - I was expecting more, and was pleasantly surprised that I never got the hard-sell. It was an offer, an invitation, no pressure at all. So...I took advantage of it with a couple of 'em. I thought "heck, I've got an hour to spare, let's see what this guy has to say." One of them looked at my situation and basically said, "you don't need me - you're obviously on top of all this". The other had some wild proposals (for example, "when we see a 10% drop in the market, we take you to all cash") which I found bizarre but fascinating. So of course I didn't sign on with anyone, and never had any intention of doing that anyway.
I hadn't been on any kind of educational campus in years either, and it was kinda fun feeling that vibe again. I also enjoyed meeting other attenders - and when I divulged that I was 4 years into retirement at the age of 60, several wanted to chat and I felt useful in providing some insights into what had worked for me.
So, maybe I lucked out by not getting the hard-sell? Heck, if you don't like what you're feeling or hearing, just get up and walk out - on the other hand, you might enjoy it.
