Greg, John,
The pool panel is just outside the back of the pool cabana. There is a storage area under the cabana where the sub panel for the cabana is located. A breaker lock would also service the purpose, however if you read the code, you are "Suppose" to have a main inside a separate building. This is another spot in the code, where you actually have to see the install in order to make the right call.
For the record, I think that most EC's would have run the feeder to the cabana, then out to the pool panel, not the other way around.
