Thinking about "hard to find a table" - at Parrot Cay you walk in, you find a table, you sit down, a waiter brings you drinks (and you don't pay for pop), you get up, get your food and bring it back to the table.
At T/BBB, you are directed straight into the buffet line, where you have your tray (and if traveling with small children, their trays as well), you are trying to herd children, get food, balance drinks - and then find a table.
At Parrot Cay, the buffet line is spread out and kind of roomy - you can skip right over the salads and to the end and grab a sandwich or hop back up and get a dessert without a hassle. The T/BBB buffet is more of a cafeteria line - with the extra stations kind of hidden (we discovered the cinnamon rolls our last day - took a while to find them up there).
