Somehow I see that the upgrade chance game sort of encourage members to book lowest category room.
For example St Regis Singapore where I currently stay.
On each floor they have 5 executive deluxe (cheapest), 8 grand deluxe, 2 lady astor room (its basically corner exec deluxe with twin bed), and 2 suites
They have 16 floor with these layout. 262 rooms 37 suites in all.
The top 3 floors are for presidential suite, premium suites and specialty suites.
It would be easy to upgrade elite to grand deluxe due to the number of rooms
Yet the chance to get upgrades further if you book grand deluxe room somewhat drop significantly.
StR Singapore has always been a special case for upgrades in that they've had multiple room categories with very little difference in price that are basically just on slightly different floors, with only the suites located on the lowest floors (maybe four or five such floors) being placed in the suite upgrade pool. Nevertheless, I've received higher category suites here (on higher floors and slightly larger, not the specialty suites on top) as a SPG Plat50, with and without SNAs and with SNAs succeeding and failing. I suspect that they overbook at least some of their room categories on a regular basis as the hotel always has seemed full when I've stayed here.
