I just wrote the hotel about this very question and here is their response ( I was impressed by how quickly they replied)
""Greetings from the InterContinental Miami Gary and Eileen,
We would be delighted to have you stay with us!
The bay view and ocean view rooms will both provide an unobstructed water view.
The difference between the two is the floor level. Bay view rooms are from floors 6-15 and ocean view rooms are floor 16-28.
Please let us know if we can be of further assistance. ""
