I personally never experienced anything when i stayed there also.......but many friends got some far out stories of shadows dancing, beds moving, flickering lights etc......the only 'ghosts' i know are those from the basement ladyboy joint Calypso.
Many folks i know also got some kind of ritual like leaving the bathroom lights on, ring doorbell before entering new room etc kind of hocus pocus......not sure if they work though........
Feedback from some seasoned travellers that they will leave the toilet lights on or table lamp lights on at night.
