We do the same thing. We go to the parks daily but only for a couple hours at a time and spend a lot of time at our resort. We never wait in a line longer than 10-15 minutes for anything, if something has a long line we just come back later. We have and will continue to go to WDW so often that we take a very laid back, relaxing approach when we are there.
Feb '01 a friend came to WDW with me that had not been there in 15 yrs, she wanted to see and do it all, so I played tour guide and we were on the go for 10 days but we still took a short break every afternoon. This same friend is coming back to WDW with me in May, she has already said she wants to go to the parks the way I normally do: a few hours at a time and then back to the resort pool and hot tub for the afternoon and then back to the parks, another resort, DTD or PI for dinner and evenining entertainment. She said the last trip she came home exhausted! I kept telling her how big WDW had gotten but she would not listen to me! LOL!! I must admit, I did not mind doing the semi-commando approach with her in Feb '01 because it was so much fun to experience WDW through the eyes and experiences of a virtual WDW newbie, but I am also glad that our trip in May will be noncommando and all relaxing and laid back.
