We usually book separate, but we also book before flights are available. I'd suggest looking at both options. See which has the best flight times and the best price and go from there. When we have looked at booking both, we didn't care for the flights that Couples offered.
When booking flights we like to get there as early as possible even if it means a red-eye flight and leave as late as possible without an overnight flight (because they are usually just long layovers). Remember when booking your flight that you will leave the resort about 4 hours before your flight.
