Interesting to compare the point spreads for “standard” rewards between lowest and highest categories in each program now:

Marriott – 7,500 to 35,000 (4.66 to 1)
Hilton – 7,5000 to 40,000 (5.3 to 1)
SPG – 3,000 to 30,000 (10 to 1)

Base earning of points without status or credit cards is 10, 15 and 2
