They've always had these promotions. Mousesavers actually keeps track of promotions going back 5 years. If you check the ones that ran for 2019-2020 leading into covid they aren't much different than the current ones, except now they have added some
Disney+ offers (didn't exist then). OrlandoParksGuy also tracks them going back even further going back over 10 years.
Year over Year data does nothing for me right now...it's data in a non-anniversary year compared to the 50th. Lets see what the numbers look like next year when we are comparing non-anniversary years against each other, but to your point...they should be down against the 50th.
