A couple blogs are reporting that Visa Infinite will work as well. How confident are you in this? The BOGO page says Infinite works, but the $75 gift card page doesn't mention it. Also, the payment screen indicates Visa signature only. Also, on the payment screen, there's a notice with a link that we have to book through my country's website-- visaluxuryhotelcollection. Can I just pay there or do I have to click the link and find my hotel all over again?
