We normally go around Easter, May and early September and mostly this is a positive change.
Even if September is during hurricane season and the risk of a hurricane impacting our vacation, I honestly dont care.
We have tried once to be impacted and that was by Irma. Our
travel insurance paid for a business class ticket home, 3 extra days at VGF - hotel side and for all our food during the 3 days. I would have preferred not to be impacted as we were under "house arrest"in our room for 1 day - think it was around 20hours so but the trade off for 3 extra days at WDW wasn't bad.
I would love to see more availability during early September, but IMHO I dont think it will happen, maybe the availability will be less now that the point requirements are going down.
