Discovery Cove Assessable Cabana - best area?

[DisneyGlitterTeacher]

Hi All,

We are headed to Discovery cove and will be reserving an assessable cabana. There is one available in the grand reef and one in the river area. Just out of pure curiosity (knowing full well a request may not be honored), which area would be the best? We would love to be able to see a view of the dolphins.

Thanks!
