Looking all adult only Caribbean all inclusive recommendations

We’re looking for a nice place in the Caribbean to go on our honeymoon this winter/spring. Our budget is 10K CAD (~7K USD). Our priority is actually probably having great food and a great beach (hopefully with a lot of seats available so you’re not fighting with people who claim them at 7am with a towel).

We do like the idea of possibly something like Sandals Grande St Lucian, where it has great food, and you can take a jeep to a volcano, and all-inclusive includes things like kayaks, sailboats, windsurfing, etc.. Does anyone have any experience here?

Anyways, would love suggestions!

Thanks all!
