That's what we did, but we've still ended up giving more money to the mouse. You see, 150 points every other year is actually a few too many points for us. So we've brought friends. We've gone in years we possibly would have taken a different vacation, because every other year really could be every three.
Its been a fine value, but it hasn't saved money - and in some ways it has limited opportunities. There are a few trips I sort of wished we'd done something else with that time and money than WDW.
