Coco Cay - Chill Island Beach Bed vs. South Beach Beach Bed

[DISNEYMAMA18]

Can someone tell me the difference between the beach beds on Chill Island and South Beach?  Last year I rented one on Chill Island and wasn't big on the water area there.   I currently have one reserved for my upcoming cruise in both places.  Other than the price and location, what is the difference?  Do the South Beach beds also include 2 loungers and an umbrella like they do on Chill Island?  I want to cancel one, just trying to decide which one.  Every time I call RC, they just read me each description.

They're all the same.
