Generally we think about the best trips... but what about the least enjoyable ones? Haha ha...

I hope you have none, but if you travel a lot, you might find some that you don't like very much.

For sure… some are best to forget! Vietnam is a great country, but I had a few issues in Hanoi. Then again, if I went back I might have a far smoother experience.

Excellent! You're right, and if you go back there, I hope you have a better experience.
