Dumb question:

I know these points are not elite qualifying (my status is elsewhere, so that doesn't matter to me) but will doing an occasional survey keep my orphan points account alive? I stay at IHG every now and then, but not as much as once a year. Eventually, I will redeem for a night at a HIX or something.

Have plenty of e-rewards but would prefer to keep them for other things, since I am an ancient e-rewards member with lots of airlines and hotels to redeem to.

Thanks.
