Hi Arti. Highly recommend the train. It's lovely scenery, if you've got the time. I had no problems with sleeping, theft, rodents or anything. It's not luxurious but it's comfortable, clean and, if you're fortunate, good company. If you take the train, the only thing I'd recommend is packing some food. It wasn't super great when I was there in 2005 but maybe it's gotten better. You can get a ticket the day of travel, but you'd probably have better seating/overnight cabin options if you reserved in advance. Hue is absolutely beautiful, too. Enjoy!
