We recently spent five nights in cabana #1 which is the one closest to the restaurant so it gets a bit more restaurant sounds than #2 but it's not bad, or too late. Hanging in your hammock on the deck of your cabana can't be beat, fresh breeze, nice view.
We watched them (queen lobster staff) buying seafood from the local fishermen right at the dock in front of the cabana and then they prepare it for you, best seafood we've ever had. Very friendly and accommodating staff.
Our only glitch was that there were some bugs that snacked on us so bring some repellant.
Things are slower in Pearl Lagoon be patient, enjoy the view while waiting.
