These are very HARD sell opportunities, they really don't want to take no for an answer at the presentation. Then there is usually a catch to the "free" trip - you have to pay the taxes, you have to pay a reservation fee, the hotel may not be anything like the description. I would not attend one of these, I've seen to many TV Consumer Alerts about them. And don't fall for the 99 dollar 4 night vacation cruise to the Bahamas along with 4 nights in the "Walt Disney Resort Area" and 4 additional nights in Vegas, Miami, etc etc. The cuise ship is usually a not very nice one, they have been kjnown tyo drop you off at the pier and you get to find your own way to a motel (NOT Hotel) and find your way back to get back on the ship to return.
There are very few freebies. Be vary wary.
PS, I know that there are honest, hardworking people who do this type thing and do it well, with out pressure or misrepresentation, and there are probably people on the boards who have bought good things, but you have to ask your self, how can a company afford to "give you airfare for 2 and hotel for 2 or 3 nights, if you aren't going to buy theor product?
