We are thinking of visiting Hanoi whilst we are also visting Thailand and Malysia. We just need a bit of advice. Is there enough to see and do in and around Hanoi for 3 or 4 days. We are from the UK can we get visa here before we travel and how much does it cost? We will be traveling from Malysia to Vietnam does that cause any issues? Also where is the best place to stay in Hanoi and have you any hotel recomendations? This is our first time to S.E Asia so really gratefull for any advise.
