What's wrong with this option? The cost is 1k or even less. You get on the bus, stock up on beer or something else, and arrive here in the morning, around 9-10.
Why rent an entire bus when you can just buy a ticket?
Cables, extension cords – that's my concern. 2 is a bit short, but it's better than nothing. Is there no way to get more?
