Le Club Accorhotels has a promotion for triple Avios worldwide for stays between October 1 and December 31, 2013.
Seems that this offer is not available for British Airways Executive Club or Iberia Plus members, but you rather have to credit to the generic Avios account.
You can later transfer Avios between British Airways, Iberia Plus and Avios accounts, however. You can access Le Club Accorhotels page for this promotion here.
Having thee different kind of Avios is confusing, but there are some advantages to this as well and you can relatively freely move Avios between accounts. The generic Avios account is only available for UK addresses, however.
