I would hope if it happens that it occurs after a planned trip. Disney doesn't fix bugs in only a month or two.
On another note, yay for no park wifi. Kinda lol on that cause I know many people need it. But kinda not cause maybe that's one of the issues keeping FP+ outta DL
I'm also hoping it doesn't roll out until after my October trip. October tends to be a bit busy and with all the extra holiday stuff and there would be no way they would be up for the challenge of dealing with all the bugs and issues in a timely manor.
I'm hoping to finally make it to DW in late 2017' and then I'll get some practice with the system that has already had its bugs mostly worked out.
