First, I would like to say that this is an awesome thread and am going to subscribe as soon as I am done writing this. This is why I love the DIS Boards! You can't get info like this anywhere else!
We are going on our 4th year as
DVC Members, but have been to DisneyWorld and
Disneyland, combined, about 20 times since my DW and I have been together.
Everything people have been saying here is absolutely true. When you are not a DVC Member, everything is rush rush and you have to cram the four parks and anything else into a small time frame. As DVC members, you have the wonderful luxury of what we have been discussing here and it is so cool that we can learn about the things people have done and experienced and lived.
My DW and I have also "slowed" down since becoming DVCers and I swear it is awesome. You really get to experience all the wonderful things Disney has to offer. Since having our DD (15 mo), we are now starting to apprieciate it all from her POV, through her eyes and even that in itself is a whole new adventure.
We definitely do at least one new restaurant per trip (It's hard to give up your old favorites) and have been taking that across all the hotels as well. We get to see a new place and see what they have there. We started doing the different tours as well, but with our DD now, there are not many she can go on at her age, so those will have to go on hold for now - unless we get family coming down with us who can watch her.

I do enjoy the pace at which we are at now - because you really do see things you haven't before or would not notice as you are rushing around.
Sorry - this got a bit long winded... I look forward to hearing about some more things that we haven't thought of yet and to trying them out for ourselves. Thanks everyone!
P.S. - try the walk from BW to Hollywood Studios - nice, LONG, yet relaxing (but not if its TOO hot!)
