They give a few free days in a hotel in exchange for your submitting to a sales presentation. They qualify those who they will allow to participate.
You must have a combined family income of 40k, and have a credit card (not a debit card). That is all.
And they ply you with images and embarrassingly false friendship, and try to sell you a package costing up to 20,000. Annual fees are higher than the "qualifying" person would spend for a reasonable hotel stay in a given year.
It is, frankly, sickening. Save yourself the trip, and instead see a movie like "Tin Men" to flavor the experience.
They have no shame.
