Well my first attempt at using the suite night rewards has been a disaster.Put in for 5 nights at the Sheraton Atakoy Istanbul at 1325 AEST.1326 got the usual pre arrival email,1327 the confirmation of my suite night request but at the same time an email cancelling my reservation and at 1328 the confirmation of my cancelled suite night request.
Now I did not cancel,even if I had accidentally clicked the cancellation button it would have gone to the page asking if i really wanted to cancel.Again as I had just put in an upgrade request I didn't want to cancel.
Immediately I read these emails I emailed the hotel and Thyetus.Today a reply from hotel saying the reservation is indeed cancelled and i need to make a new one.But this is a prepaid rate so not going to pay twice.
Have now emailed customer care.
So indeed it seems the suite night awards trigger an automatic process but not the one I wanted.
