We'll be going this November, and I'm hoping to talk hubby into adding Orlando to our Miami trip next May. He doesn't like being away from work two weeks in a row, but agreed to it in November because we haven't been since January 2013. I'm kind of sad to lose the Streets of America, but we're looking forward to all the Star Wars stuff. Don't feel like the construction at Animal Kingdom has changed anything significantly. Looking forward to seeing Rapunzel's bathroom and the Mine Train, which weren't open last time.
Construction was not a factor in our decisions at all; I'd like to visit Disney World (although not necessarily the parks) every odd year.
