The only times we were upgraded was during the Covid mess. Long stories, but for 1 trip we had 3 ASSp and 1 CS rooms booked (extended family) and got the best upgrade ever to the Poly, which then turned into studios at the Poly.
For another trip we had about a month later we had again booked ASSp, which turned into a family suite at AoA, which then turned into a 2 bedroom SV at AKL.
We also had a 3rd upgrade from ASMo - AoA, regular room last winter/spring.
We felt beyond lucky with the first 2 upgrades and it was awesome...it also really probably did them a favor as well because we've since spent the money to stay at the Poly again which I highly foubt we would have done without the first stay.
