I don't travel for work any more, but I still prefer staying at Starwood hotels. I have lifetime gold, which doesn't count for a while lot, so it's mostly just the familiarity with their hotels.
I guess jeans - all my jeans have been Lucky brand for the last 10+ years. They're really soft and comfortable, and I like that.
My wallet - it's essentially two pieces of metal with a hair band holding them together, but i absolutely love it - it's exactly what I want. So I'm on my second one, even though it's really hard to find.
And I guess I really only go to one movie theater - but that's more because of the assigned seating than real loyalty.
I'm sure there's others, but that's what I can think of for now.
