Other people (adults and children, foreign and Vietnamese) will get in the way when you try lap swimming here, regardless of the time, dawn or dinner-time and every hour in between. There are no designated "lap" v. "play" or "lounging" lanes or times. You can politely ask them not to impede your progress until you're blue in the face, but they still get in your way. You can request help from the reception desk but they just stare at you and do nothing. In my usual one-hour swim, someone got in my path about every five minutes on average.
