Very surprised at the speed of redemption at the Marriott Marquis New York - I apologized in advance for having 3 separate cards to redeem (from various family gifts + my Ambassador yearly gift). The FDA said no problem, typed like a whirlwind, verified the balances, and emailed me my new receipt within 2 minutes. So, it definitely…can…be easy to redeem these if the agent is informed of the process.
