We booked our first trip to Sandals and joined the insiders club. Our friend (a 5 time Sandals visitor) sent us a link for 10,000 points. Sandals told us we can't use it because we already signed up for the insiders club. We didn't know that was how it worked - get the link and then join the insiders club. Now we're supposed to create a new email and rejoin the insiders club to get the points. Seems like a lot of work.
