I paid a discounted rate to upgrade from a concierge room to a 1BR suite at check-in, and then they upgraded us to a 2BR suite for free.
A few notes about this and why I don't think it happens often:
1. It was my birthday, and I'm a repeat AKL concierge guest .
2. The second BR connected to the LR of the suite. The way it was set up it was not rentable as a guest room without the suite. So it was going to go empty anyhow.
3. Unless I'm very mistaken, the suites at the AKL are much different than those at the WL. They are larger and offer more amenities.
4. Like I said, I paid for the upgrade to the suite, the second bedroom was a "toss-in". I don't think that they give free upgrades to suites very often if at all. I also would never count on getting the extra bedroom, it will be pixie dust if it does, but I'd hate to have anyone plan a trip around it and be incredibly dissappointed if it doesn't.
