I'm about to download the online application for the TIW card. I know it's good for 1 yr, but when does the ticker start? Is it when they send me the card or when I first use it, like an AP? Also, if I use it in addition to the DDP (for drinks, apps, etc) at each meal, will they add the 18% gratuity to the entire bill, including DDP items? Also, am I right in assuming that I can use the card on a b-day cake? Thanks!!!!
