I have confirmation! An amazing rep just let it slip on the phone.. I called in to proactively to add Park Hopper to my base tickets and told her just in case it is required for FD.. The rep let a bunch of information fly....
"You are also able to add Water Parks if you would like to take advantage of the Free Dining offer this year"
She caught herself and then for the rest of our call used the phrase "historically" I'll bold what the rep said to me
She Stated
"Historically if you have a modify button then midnight of the day a new discount is released you can do it online. I'm going to be looking at mine in about an hour"
"For your dates I am comfortable switching you to the POR and you will be able to take advantage of the FD offer"
I'm going 9/9 - 9/14
I asked if my current 4 day ticket with added PH would be enough for free dining because there was a rumor about a minimum of 6 nights and she laughed and stated
"That would be a little excessive and you can rest assured that your current ticket will allow you to take advantage of the offer... Historically it has been 3 nights"
She was obviously using the word "historically" as a wink wink
If you have a modify button I'd check my res in about an hour, if you don't Id be prepared to call bright and early. I normally don't say things are definite, but she gave me every hint she could without saying "Yes i'ts here and call tomorrow"
