I'm the opposite, because I'm Australian and we get twice as many weeks vacation each year as Americans, during which time my wife expects me to use my Platinum status for family holidays.
Hence so far I've accumulated 61 nights in 2006 but across only 15 stays.
And that is a bit of a bugbear for me. I don't agree with the program being aimed exclusively at low-rolling road warriors: I think that there should be multiple pathways to Platinum which give extra credit for staying in hotels of each higher Category (e.g. Cat 4 counts double, Cat 5 counts triple and Cat 6 equals a 400% stay or credit bonus).
After all, 13 nights at the W Maldives or St Regis Bora Bora should not be valued less than 25 one night stays at Four Points hotels.
