Yep everyone is right, last year we went for 7 nights but got 8 park passes for the 8 days and we thought that would be how they worked the number of meals. We even made ADR's for 8 TS meals. When we got there the itenery read 7 ts, 7CS and 7 SC, Each. We then realized that it went by the number of nights of stay. Got to the last day and still had 2 CS each remaining so we canceled the 8th ADR.
There is so much food it is hard to believe, but had such a great time we are staying 9 nights this year and we do know this time it will be 9TS, 9CS and 9 SC. Just make your ADR's ASAP.
