I believe the regular checkout is 11. Not sure about that as I always leave late.
Oceana is awesome! Last time I was there I was alone, sat at the bar and let the bartender suggest what to eat off menu & accompanying wines. Then I walked to Rum Shandy, had a drink and listened to some great music.
For many years I stressed about making it to the airport on time...ferry schedules...returning rental car....etc. Now I just tack an extra day onto my trip and it takes all the stress out of the situation. Also I am much less tired when I get home.
