My fam went to WDW last year the week after Thanksgiving. I used Josh's crowd calendar to schedule what days I went to which parks. But once I was down there, I used the TP app to help me to know which rides were backed up and which ones were not. It worked well. It was a good week to be down there anyway, from a crowd standpoint. But we were never in any park that had above a 4 or 5 and never waited longer than 15 minutes to ride anything we didnt have FP for.
