Before moving to Belize, i traveled to many caribbean islands. My husband and i ALWAYS went to time share presentations to get the freebies

we thought it was great...still do. just depends on the time share company.
When i have friends and family visit, i actually send them to Captain Morgans for a day. I tell them that they will get a tour and $100 USD bar tab and can hang up north for a day. Very Low pressure sales, just a tour, and a nice lunch.
These give aways can be great, but i do think you have to look before you leap. Ask questions...NOT of your salesperson, clearly they have an agenda. Walk into any bar or restaurant on the island, walk down the street...ask ANY random stranger who lives here about certain properties, and then LISTEN to what they have to say.
