thorag, the announcement noted only the SM MoA rink, so I think it's that rink only. There is another SM Mall rink in Metro Manila (SM Southmall) but AFAIK it's not Olympic-sized. There was no mention of another rink being used in the e-mail I received, just that the first 4 days were on-ice and off-ice training, while the last day would be the competition proper. I am supposing that while the event is going on, commercial activities will be suspended. And to maximize the ice time, the participants will be allowed before/after the usual mall hours.
