Don't feel bad about only going every couple of years - I've only been 6 times in my life in total.
1980 - family trip, 2 days, Contemporary
1993 - 2 day-trips while helping friends move to Orlando for college
1994 - 2 day-trips visiting same friends
2001 - 4 days on my own, All Star Sports
2006 - 40th birthday trip w/bros & sis-in law, Coronado Springs (5 days)
2007 - latest trip, 6 days at Pop w/brother
Going to WDW has definately has not lost it's magic for me. My youngest brother went for the first time last year at age 22 and he's completely taken in by the magic enough he went last month without me!
I'm pretty sure I won't be going this year, so going forward if I can save enough for every couple years I'll be grateful.
I can see your point though, Tubageek that if going to the World got routine for me I'd probably take a break, but I can't see that happening any time soon.
