Interesting discussion..
Today I am SPG-Plat and HH Diamond. Marriott just gave me (yes gave me - no status matching) PLAT in their program and I am debating whether to lock in to them in 2010
Hilton is good on benefits (lounges/breakfast) but the room upgrades are a real hit or miss. SPG customer services have taken a nose-dive - they outsource to the Philippines and Caribbean countries - I want to talk to people in my own country
Is it even worth pursuing Marriott?
