FamilyMoon,
Sorry to hear you couldn't get the rate. But to tell the truth, we were actually a bit relieved that we couldn't get it! We'll be paying a bit more at the Hotel Royal Plaza, but we've stayed there previously as well and it is much more upscale.
We have a great deal with the Royal Plaza (which is right next door to the Courtyard)-- buy three nights get one free, free upgrade to deluxe tower room, $69/night rate, and the $7 a night resort fee waived. So our rate comes out to $51.75 per night for 4 nights. I don't think that entire deal is still on, but you could call and *enquire.* You can find their phone number by doing a google search for downtown disney hotels and then clicking through their website to get to the link for the Hotel Royal Plaza.
I've never stayed at the Raddison Resort, so can't directly compare it to the Royal Plaza, but if you are looking for the DTD location the Royal Plaza is a good bet. Even if you found a rate around $100/night at buy 3 get one free and got them to waive the resort fee, you'd be pretty close to the rate you're paying at the Raddison. We stayed in a regular (ie, non-tower) room in the Royal Plaza in the past, by the way, and it was perfectly nice.
As to that *enquire* thing-- I believe this is the preferred spelling among Brits. Since the OP told us to mention some website with a .uk suffix, I would speculate that we may be dealing with a UK website. The time difference might explain why they didn't get back to you (isn't it 7 hours later over there?). Perhaps they were closed when you contacted them...
