Although I'm sure I was probably well informed at the time, my account seemed to get switched automatically from 500 miles per stay to $1 per mile. However, I have changed it back nicely to 500 miles per stay! ^

However, you have to ask yourself the question, if you're spending $500 per night (giving you 500 miles if you chose that earning option) is there really any point in being an HHonours member? Surely a couple of free nights a year are going to be a drop in the ocean......
