Hilton Honors was a weak loyalty program to begin with. It was less rewarding for your spend than you realized in terms of free nights earned – it offers lower rebates for both general members and for top elites than the other major chains (I show my work) – and more modest elite benefits than Hyatt and even the consistently inconsistent Marriott.
However what Hilton had going for it is breakfast. That was offered at all brands, without exceptions, and offered even to Golds. Gold is more or less a giveaway level, available via many credit cards and historically bundled via a number of promotions.
