I'm pretty sure your coupon sheet is tied to your play. We too used to always hit the coupon sheet at Casino Royale on our trips to Vegas. Once they completed all the upgrades and expansions, the coupons went to all slot machines, none of the nice VP coupons they used to have. When we were in Vegas late January this year we picked up the coupons to see if anything had changed, and nothing had. However the guy sitting next to me at the bar had a coupon sheet and his DID have several VP coupons including a 4OAK.
