Get out of DT. "Block of rooms" is often a racket, because there's rarely any huge price savings from that to if you just do your homework and get a good rate from a travel site. DT is not the place to be if you wanna go to WDW. I-Drive or closer, period.
We stayed offsite, and we were totally fine with the traffic. No biggie at all for us. But I'm from Chicago, where traffic is so heinous that everything else looks good to us :-). But there are great benefits to staying on property. I, personally, would love to stay on property one day, but my taste in hotels precluded us from doing that, as it was way too expensive. We stayed for free on points at the enormous Marriott, but we were prepared to pay for a few hotels we'd narrowed it down to, and it was less than WDW, worked out to something like $150/day. But I'm a hotel snob, so take it for what it's worth.
Bottom line, DT is not where you wanna be.
