This exactly! My first visit was 2011, when I planned to go back in 2012 I said I'd be fine to wait a while and explore more of the world before heading back... that clearly didn't happen so WDW visit #6 is coming up in November and #7 being in early discussions. It's the main reason my partner and I broke down and bought DVC, we have skipped
Disneyland on previous trips and didn't miss it at all, but no trip to the US is complete for us without a WDW visit.
I'm from Perth as well! You're the first Perth person I've come across on here
It's a
very long journey and the one downside of visiting WDW in my opinion
Since you're staying on property, definitely take advantage of the My Disney Experience perks like booking dining reservations and fast passes in advance. Also recommend following other peoples' directions and go to Mickey's Not So Scary Halloween Party. I've only ever been to the Christmas party, but Disney goes all out for their holiday events and I'm sure it'll be fantastic.
