Bimini: which way to spend day?

[RedRox]

Considering either:

 

the pool/beach resort day for $40 pp

or

a simple cab to radio beach

or

if we are feeling adventurous, the snorkel with sharks (but more likely one of the first two)

 

any opinions?

we will be arriving as two adults, very end of July. 
anyone know the cost of chairs and umbrella on radio beach?

Cost of beer?

Is there a convenience store we could stop at on the way to the beach?

 

thanks!
