I like Hilton Hhonors, because of the two-way conversion it allows of FF miles and Hhonors points. (I almost always convert FF miles to Hhonors points, since airlines make it almost impossible to use the miles.) Hilton has a good mixture of properties in terms of locations and types. I do wish they had more Homewood Suites and I wish that their franchised properties were more complient with the benefits the Hhonors program offers to elites, but I have never had any serious problems in my stays.
