Has anyone else had issues with being unable to modify a WDW reservation to either Aulani or VGC? I am not actually trying to book there, but while modifying an existing reservation that is well within 7 months, I noticed that both those properties are greyed out. If I try to book a new vacation for the same dates; then all properties are available. VGC is also showing in my home resort section; but that is due to the existing reservation using one time use points. I'm just thinking down the line, I could see myself booking a WDW vacation at my Florida home resort; and then trying to modify it to VGC @ 7 months if availability is there. but this would prevent that from occurring; and with Disney IT, I'm wondering if it is an issue that won't be fixed on its own.
