After getting into Hoi An on the night bus I found that quite a lot of the hotels were full, particularly all of the budget options. The best I could find was $15 per night. I know that most of you are thinking that's a great price, but up to now I've been paying $7-$8 per night.
Besides, I'm in SE Asia, things are just plain cheaper here.
Conical hats, colonial architecture, bicycles and scooters. That's Vietnam.
