With that late of a flight, I'd definitely go to a park. Are any having EMH that morning? Could go early, stay through lunch and then head back to the resort for some leisurely last minute gift shop browsing.
I have an S8 and it has a great camera! The battery life is also amazing, even over a year out. Not sure how it compares to the iPhone 7 or Pixel 2, though.
Oh, this explains why I couldn't change my signature or avatar! It's been so long since I've done anything but lurk, my post count must have gotten reset.
