I haven't decided if it's a good idea or not yet (I am leaning towards bad idea) but there is at least one investment fund aggregating those units as a shadow hotel. Fire off lowball offers to those desperate to stop the bleeding.
For someone with some money they don't need for a while, being part of that pool may work out. I don't think the hotel idea will work well (as Toronto will try to shut it down) but lowball buys followed by liquidation in a few years as market rises might pay off. It's not a guaranteed play though. Unless the lowballs are <300K per door, it's really hard to justify condos as investments to rent out.
