Hi all. First things first, are you allowed to use the free diamond upgrades to 'upgrade' a 3rd party booking? I guess not. So, are you allowed to use a BRG for the base room, and then upgrade that?

I'm looking to stay late September for 10 nights, i'd also book a weekend somewhere to complete the '12 nights' in 60 days requirement. However, i'd love to be upgrading that 10 night stay itself, with two of the free suite upgrades. Will it still be 'qualifying' if I do manage to upgrade it?

Oh, and when is best to apply for the challenge for my late September 'plan'?
