IC LeGrand
Upgrade: To a junior suite, which is a very large room for Paris, very well appointed. Same as when paying.
Minibar? -- free as an RA on award points including good Champagne. Minibar generally well stocked.
Club Floor: No/not offered, but then again I have not found that to be an RA benefit unless there are no suites to upgrade to. You can purchase access to the club for, I think 70 euros (for one)/120 euros (for a couple) per night. No special rate for RA's unlike the Mark Hopkins, for example.
