Depends on how you define "trip." I'm fairly local, so I've been loads of times for day trips, but the last time I did a proper WDW vacation over multiple days and a resort stay? I honestly couldn't tell you. I know I went for a solo weekend trip in 2011...and I know my family hasn't gone since 2013, but I can't remember if we did anything in 2012. So it's been six, seven years for an overnight stay. And I've never stayed longer than 3 nights in a row, so my upcoming 5 night stay is a big deal for me.
