I spent almost all of my Le Club points on a European vacation last fall but have 3000 points expiring on October 7 and I won't be staying at an Accor property before then.

Is there any inexpensive way to extend with a small purchase?

Alternatively, is there any way to spend just the one voucher? I read in another thread that you can't use a voucher in a Sofitel restaurant without an accompanying stay - is that still true?
