Crap, I re-booked my Hilton ressie in Miami through Orbitz for this weekend... only to discover that HHonors will not credit Orbitz stays!?
I thought it was only PL (opaque) bookings that were not allowed. For the mere $38 savings (that was all it added up to with differing tax rates) it wasn't worth it. I wouldn't have gotten my room upgrade/Executive Lounge acces either.
Ended up calling Orbitz back, canceling the reservation, and requesting the $25 fee be waived as a "one time courtesy." Then re-booking with HHonors.com. Including the half hour debate with the HHonors CSR, that was a good amount of time wasted!
