I enjoy the NA based brands. As a TA, I can get top tier benefits (free breakfast, upgrades, hotel credits) etc. which makes the HERA program more like Hyatt Globalist and beyond for anyone! I usually only get to Gold or Silver status based on my $ spent, never nights.
I agree, you would have to stay so many nights in NA but your $ spent would more than make up to get your status going.
my favorite NA locations are the Faimront Mayakoba, Banff, Scottsdale, Austin and hopefully NYC after an upcoming stay this week.
