Hilton has a great point system, but currently lacks the locations that Marriott offers. Wyndham has a point system with many resorts, mostly on the east coast and Worldmark with resorts on the West coast.
If you'd like to join your neighbores in Aruba, I believe Aruba weeks bought through Marriott resale can still be enrolled in the Destinations club without an additional point purchase. Not as cheap as resale, but cheaper than buying trust points.
So our neighbors just bought into Marriott in Aruba Surf Club and we really like the idea of owning a timeshare. We are trying to determine what will be best for us to purchase. We love the Marriotts and the flexibility of the points system but it seems like they've made it impossible to buy re-sale. Thoughts? Is there a better points system to get started in?
