i used the orange promo last year to get silver elite for a stay in Malta last may. i dont often stay in radissons and havent used it again since. but am now looking at a couple of stays where it could be worthwhile. I cant see when i got silver on my profile and dont want to nudge then into noticing its expiring. does it generally just disappear after a year? can you use a promo to get it back again? thanks
