Back in the day when I lived in the Midwest, we went 3-5 times a year.
Since we live out here by DLR, now, we do at least 2x/year here, and then try to get to WDW to visit family and friends at least every 18 months or so.
This year we are giving our normal WDW trip to our best friends points to use as one week of their 3 week WDW honeymoon. It's their first time to WDW and over Christmas through early January to boot! (It's the first time I've ever given points to anyone - we always go, too - and I've owned for 15 years!!!)
They're going to have a fabulous time! We'll go for F&W in October, instead! It'll be the last fall that we can go without pulling someone out of Kindergarten! (OMG - I can't believe I just said that!)
