Choice redemptions - from the e-rewards website "You may claim one (1) Choice Privileges Reward per calendar quarter, per Choice Privileges account and/or e-Rewards member account".

I had been hoping to credit e-rewards from two different e-rewards accounts to the same Choice account within a few days (Grand Slam hit). This suggests I shouldn't be able to. Is this enforced in practice and what would happen if I tried and failed - would my e-rewards disappear into the ether or would the transfer just never happen?
