What I do, is I watch Disney movies quite a bit from my collection, I watch my planning vid alot, I look thru old park maps, old photo albums of previous trips, I take old maps, reciepts, pics, etc, that I have laying around and I make scrapbooks out of all those things,
I read disney planning books (Official Guide, Unofficial guide, Passporter, etc)
if you dont have any of that, then you can start a planning folder...I went and got a BIG disney 3 ring binder (with Tink on it), and I got online and started printing certain things like park times, menus from restaurants, my pressed penny list, packing list spreadsheet, disney tips, hidden mickey list, etc and I made "sections" in my binder with britely colored separators...(all dollar store school supplies) so, now I have this huge binder that I mess with every day, and it seems to help me!!
One other thing, I made a DISNEY CHAIN! out of construction paper, and I cut about 1 inchx6 in strips and every link I have like 10 days til PIRATES OF CARIBBEAN ride...and 11 days til DOLE WHIPS! etc...so every day me and my hubby (no kids) pull a link off and we ARE ONE DAY CLOSER!
Try that, it sure helps me!
