My information is also a few years old but if you are thinking of going for three weeks, just check out the prices for annual passes to DW. In 91 when we went it was the best price and it was good for a year so you could go again 11.5 months later. Also included free parking and a few other perks. As far as I remember, they weren't really advertised and you had to go knock on a back door somewhere to get one. I suspect they were really meant for locals. But all may have changed since 91 of course.
