"The idea is that you insert the two US plugs into GPO's around the room in a random manner until you found two on separate phases; ie. 240V."
Aussie, most US hotel rooms (at least in larger hotels) are derived from a 208/120 Y. If you try this and are actually able to get two phases, you will probably not end up with 240V.
Likewise with Marc's idea of using a NEMA 6-15 plug. These are often used on 208V circuits. I wouldn't try either of these options without first checking the voltage with a meter.
