While I do not have the 2005 UG to WDW, an acquaintance provided the following info to me for my upcoming trip.
11/20 and 11/21
- Crowd condition: 2 (Very light)
11/22 and 11/23
- Crowd condition: 3 (Light)
11/24
- Crowd condition: 5 (Busy. Crowds affect major attractions)
11/25 and 11/26
- Crowd condition: 8 (Very crowded. Expect waits of 45-80 minutes for headliner and major attractions).
Having gone to WDW Thanksgiving Week on multiple occassions previously, the above info matches what I have experienced.
