I just started using LNF in the past week, so my sample size is rather small. But I am batting 100% (2 tries, $433 savings, no issues) on USA properties, but 0% (4 tries - they nit-pick that the room descriptions are not 100% the same, currency conv issues, etc) on non-USA properties. Are others seeing this (I do see in this thread Amersterdam and S Korea recently, so know it can be done). Are there any special secrets to the non-USA properties? Thanks.
