PC Platinum? What program is that?

In terms of Hilton, with only 10 stays per year at 1.5 days per stay, you're not looking at a week in Europe. That should get you something like 25k miles. Once you get an elite level, there will be a bonus, but they don't just hand you a week in Europe for nothing. You will likely be a good few years before you get a week anywhere really nice. I think the 25k miles will get you a free night. It really isn't that easy to just get free hotel nights. Getting flight benefits is much easier.
