Paradise Island
 

Of these 2 which would be a better resort on Paradise Island, Nassau, Wyndham hotel or Club Land"OR". going with 2 teeenagers 17 and 14. Never been before

Wyndham is not on Paradise Island, it's at Cable Beach. Club Land'or is an old worn out timeshare located outside Atlantis. Older crowd.
With teens, I'd opt for the Wyndham. Lots to do.

If you can afford it, because it is very expensive, the Atlantis would be a hit with your teens. The food is good and they have the slides, pools, beaches.

If you stay at Club LandOr, you have full access to EVERYTHING at ATlantis, without paying the fullprice of the resort. Club LandOr is a bit of a walk to Atlantis, but your kids will LOVE staying there and have access to all the pools, lazy river, and since it's a younger crowd there, will find friends to hang out with.

Have a GREAT TIME.

Land'or no longer had full access to the Atlantis, they only let you use the pathway from the Beach towers and use a chaise lounge on the beach. You can't use the pools or slides anymore.

Comfort Suites has full access, it's the only non-atlantis property with these amenities.
