Its a hard act to improve the environment at the show actually. Imagine this, the only way one can showcase their system with full blast with minimal interruption to your neighbours would be a room. So hotel comes naturally in this respect as a show venue , not KLCC convention hall or other open space venue.

Its easier to control and to clean up the environment in one open big space, but its not going to work in a hotel environment.

Then the size of the room and the resources comes in too. I have seen the staff actually stock everything inside the hotel room toilet, they even eat their lunch there ! So do expect difficulties and lack of facilities to provide good environment for the customers. I mean, they can't even keep their own show room due mainly to lack of space.

As a customer, I would expect draw back such as this. Nonetheless, its always good to point it out for future improvement sake.
