Well after many months of browsing I've finally joined FlyerTalk!
I got the Hilton Visa just over a year ago. I got a sign up bonus of 20k points... would rather the free night offer they have now.
To answer a few questions...
Points show up on your paper statement, but don't seem to show online on the card account. Point are broken down into normal/ bonus, so for example if you spent £300 with hilton, you'd recieve 600 points and 300 bonus points.
Not had any issues with the card, and used the 3 stays in 90 days offer to get Gold earlier this year. I use the card for all my spending and it's quite impressive how it adds up. Due to the (potential) value of hilton points, I often calculate it's worth paying credit card fees to use the card on large purchases.
All offer bonus points etc. have shown up practially instantly.
