We don't fly that often...
In fact I'm quite sure all of our accounts are due to expire if they expire after 18 months - is there a way to check this online?
My Daughter's will surly expire as she is not making the Venice trip(4yr old).
I thought I read somewhere here about transfers to Hilton Rewards - but I am not able to find it now.
Any further suggestions??

Thanks to all for your expert advise!
