For a level 3 They seem to be quite good, depending on occupancy. I book the cheapest available and have had some nice upgrades. But to be honest I dont expect anything as its all work-based stays, and anything else is just a bonus.
Was 6 nights away from top tier on Oct 14th, now the goal post has moved to 13 nights by Nov 6th, which I will fall short of by 5 or 6 nights again..So close but so far..

Thanks for the info on Nordic, looks like a good back up for the future.
