The ML all night, as a one-off, is on my bucket list. There are about four MLs that I'm very chummy with that I reckon would be receptive to the question. To be honest, I can't get out the room fast enough at the end of the hour. I'm likely going to bin that idea or save it up for overseas.
I base mine on budget. so once a fortnight i visit ML. if you do it everyday it maybe better to have a girlfriend instead. it helps your wallet in the long run.
