Can u swim in the water next to hotel or it's shallow water ,is the beach nezt to hotel with white sand?

Yes, you can. It gets deep quickly, unlike in Crandon Park. The sand is white. Obviously, there is some seaweed lying around.

The water was thigh high and had small fish swimming around when I went out.

It does have a narrow shallow part. As all oceans you have to be careful of bul sharks and jellies ...as well as rip tides .of course it still has beutifiull sunrise and pool beach side

Yes
