Has anyone who has gone directly from HaLong Bay cruise to the Hanoi Airport done any sightseeing or excursions? We will have had 2.5 days in Hanoi end of June prior to our 2 day/1 night HaLong Bay trip, after which we are flying to Hue 7:30 p.m. from Hanoi airport. Since there may be a couple of hours to see something of more rural northern Vietnam, wondered if anyone has any suggestions or has done this. A nice place to stop and explore between HaLong Bay and the airport? Many thanks.
