I haven't seen one but I made a table in Microsoft Word to keep track of what we're doing. I had thought about making one just for ADR's but this is better.
There's a column for each day, and then on the far left column the rows are labeled for Morning, Lunch, Afternoon, Dinner and Evening, then in blue print: EMH Morning, EMH evening, Spectromagic, Fantasmic, and under those, a row for each park and their operating hours for that day.
It all fits neatly on one page, and that we I can keep it folded in my pocket and know in a second when everything is and when things close so we can plan accordingly if we want to hop to a different park than planned.
It's not hard to make but if you want it I could email it to you. It's more information than just our ADR's.
If you want to make an Excel sheet I'd make a column each for Time, Restaurant and Location (Park) and rows for each day of your visit.
