I went as a child several times, but my DH's first time was our honeymoon in 1994. The look on his face was the best wedding present I received. We've been going every year since except 2000. We stayed off-site for our honeymoon, the Radisson Barcelona on I-Drive because at the time my husband was a Radisson employee so we got the room for $33 including tax. Then, in 1995 we went back and stayed at All Star Music. I think the next year we did CBR and fell in love! For a couple of years, we stayed there only. One year we went to Siesta Key, FL (gulf coast) and stayed off-site in Orlando. NEVER AGAIN did we stay off-site when visiting Disney. Since then we've stayed at CSR, CR, WL, Poly, YC/BC, GF, Swan, Dolphin, POR and OKW. Our favorite is the Poly followed closely by YC/BC and followed closely by S/D. We like to change from the MK resort area to the Epcot resort area..keeps it interesting. This year we stayed at POR because the budget was limited....very nice resort!

We usually go 2x a year on average.
The magic increases for us. My DH always says as soon as we return home: "I could go again next week and be just as excited." I will say I've noticed some things are slipping, but I won't get into that because that is not the topic of this thread. That said, I STILL love WDW and will continue to go back. We do like to go other places as well so sometimes we combine a beach trip with our WDW trips.
As others have said, it's so nice to know that we don't have to rush because we'll be back in about 6 months. We tend to go every 6 months or so, sometimes a little less or sometimes a little more. Some trips are week-long some are long weekends. It's a 9 hour drive for us so by long weekend I mean 4 nights. Can't imagine driving 9 hours for 2 days. We'd have to fly for that type of trip, which we've done a couple of times. We don't have kids, and we don't like going with other folks. Went with my mom and aunt once and it was a disaster.
Some of the attractions are old hat to us, but we have our faves that we hit every time and wouldn't miss or the trip would be incomplete. We like to visit the resorts, take part in the recreation like horsebackriding and boating, we like Fort Wilderness a lot (love the Campfire Singalong) and we definitely like to eat and shop. Oh, and play minature golf at Fantasia.
I hope we NEVER lose the magic.
