Don't have any affiliations there at all. Any websites you know of good for that? And do those rates still earn benefits and points?
Otherwise, if the 100+ rates are just fact now, it is best to use points. I started playing around with dates in Jan/Feb for EZE and Mar Del Plata and it would seem I could do 10 days (Cat 2 in EZE and Cat 1 in Mar Del Plata) for about 30,000 points! I realize it's tied to equally low rates but man that seems like a deal
A couple days in Iguazu would make it a bit less sweet as that is Cat 3 ;-) Too bad there's no *wood in Punta Del Este.
