I guess we are a non-traditional tradition family! After multiple trips (as a kid, couple and now mom..) we choose to do something that we haven't done before. Every trip there has to be something new, this way we keep DL fresh and there's always the excitement of the unknown in every trip.
Granted, this is easier at WDW, where I could live a lifetime and never do it all...but we find this easier than you might think at DL as well. Even with multiple trips per year, there is always something new to experience. Whether it's a new restaurant to try, ride, show or parade to experience, or new hotel, guided tour, etc...
For our trip in December, our new-to-us things were - Ralph Brennan's (fantastic), saw the Holiday Parade (also great!) and stayed at the Anaheim Hilton (a very nice surprise!)
For my daughter's birthday weekend (March 2nd/3rd) we are trying Trader Sam's for cocktails, Ariel's Grotto for breakfast, the Fantasmic Dessert Seating and the Walk in Walt's Footsteps tour.
Anytime we feel like we are missing out on an old favorite we tell ourselves - we can always come back!
