For the $500-$750 you save with the credits you can buy a lot of taxis! A taxi should take only 15 minutes or so, depending on traffic. Our only regret was not staying later to wander around town at night (and more restaurant options). What if you spend 2 nights at the WA for free and then move to town? Christine at the WA was terrific help in getting the space we needed without having to get a suite.
