I mean, don’t go to one if you’re susceptible to this sort of sales presentation. If you can withstand two hours of a pressure cooker, you can get an excellent deal on a multi-night resort vacation.
Timeshare salespeople don’t want to waste their time trying to sell to someone who knows what’s up, came solely for the promotional gift, and is categorically not going to buy. Sometimes we had to refuse to play their numbers games, when they asked for our income so they could “show” us just how good a deal their crap was, but we never had to sit through a full presentation.
We went on a fun, totally free cruise courtesy of one of those companies. Good times.
Big mistake.
Don't assume it will be only two hours.
I did once pay to go to a 3-day RE workshop which turned out to be a sales pitch. And oh boy, when it comes to fantastic presentations, this was the best. They're basically trying to sign you up for mentorship at a cost of $35-50K, so I can see they've got money to make it fancy and hire top salesmen as well as entertainment equipment. It was basically a 3 day long show. If they'd made it a lot cheaper (e.g. $15K), I could see myself falling for it. Who doesn't want to get rich, and what they were offering was sound (except for the fact that most people who pay don't have the discipline to follow through on RE work).
It wasn't very pushy, though. I had a brief 5-10 minute 1:1 with a rep. Perhaps he sensed dirty tactics wouldn't work for me? I did hear from another attendee that their meeting with (another) rep was worse - along the lines of "You're saying No. Do you want to be the type of person who always lets opportunities go by? When are you going to change to better yourself?" Had they said that to me I would have gotten up immediately.
Although I was annoyed at being duped, I actually did learn quite a bit about RE in those 3 days. It was something like 35% real education and 65% sales pitch, with the education scattered in between throughout the 3 days.
Of course, one could learn it all themselves. Plenty of cheap/free resources. However, there was value in having it all presented in one place.
