I find this true at most chains - insufficient staff for the dedicated elite line though if there are 2 staffers at the front desk you normally see 1 dedicated to the elite line.
To be fair I have never seen the kind of checkin lines at Hyatt that you see in Vegas where dozens of people are waiting - more typically my issue is that I arrive mid-evening and there is only one person at the front desk who is busy dealing with somebody that has a complicated checkin
But 90% of the time I walk straight to the desk, no waiting!
My bigger complaint is the failure to pre-assign the best rooms to elites, or conversely receiving worse-than-average rooms because the front desk doesn't care or doesn't think I will notice.
