You should. We paid 41 USD for the tour and there were 25 people in a tour. I'm not sure how much they pay for the council to rent the house. Yet I think they make pretty good money in short time ( 1.5 hour/ tour) and 2 tours/ night, lol.
I never heard about any ghost tour in Vietnam tho but it may be a great idea for thrilling experience and people like to explore it. :)
Now that's a business! You'd have thought for that sort of money, they'd have a member of staff dressed as a ancientbwench carrying her head under her arm!
Lol, no need to dress up as the place is guienely creepy with many spirits in 1 place 😃
