There is this promotion at priorityclub.com/delta.

The thing is, I've already booked a stay at the InterContinental Rome through Priceline and paid for it already. If I join now, will my stay count for points or will I be able to get the benefits of Ambassador Status? Or does it count only if you book directly with ichotelsgroup.com?

Does this status give you a break on Internet access? They're quoting 10 euros per hour or 18 euros per day!
