Thank you for your response. We're wanting to hit Hollywood Studios and Animal Kingdom as well as Magic Kingdom and Epcot. It would just be our family of four. I know that with the way my family is, that I'll exhaust myself trying to get them moving quickly and on also keeping to a schedule, so I pretty much have to leave a lot of room to rest and relax. Our family would enjoy seeing the countries and shows, but also the rides. I do remember as a child, LOVING Epcot and in fact, wishing that we could have spent an extra day there (this was YEARS ago, well over 25 years ago), but I don't know if it's changed a lot in recent years. So, I guess I was wondering if six days gives us time to see a lot of what Disney has to offer and if taking a couple of rest days to hang out by the pool, or go to Disney Springs would be a good game plan.
I think that the best way to begin planning is to get a book, as PP's have suggested. I also woudl pay very close attention to the theme parks board here becasue I believe that with all the changes happening the parks are going to be busy, with no real slower times.
I would plan for how your family likes to tour. For instance, we have been several times in January and in December, and for Thanksgiving, as well as a few times in October. The timeing depends on what your family wants to see. We like the Holiday events and decorations, so we tend to visit in December, or for Thanksgiving into the first week of December, but that means we take time for resort hopping and visiting the WS to enjoy the holiday kiosks, decorations, and storytellers. For us, Epcot is multiday, as is the MK. There are parties going on in the MK so if you want to see the evening entertainment, I think that hoppers are teh way to go. You can RD one park, head out to swim or relax a few hours, and pop into another for dinner and evening entertainment.
EPcot is my family's favorit park and we tend to spend at least one day there and a few evenings. It is lovely at night.
Animal Kingdom is a half day park for some folks but it is a park we visit at least twice a trip. WE do not spend all day there, but we are not those folks, so we will usually go two times, and try to be there once in the evening for a little while at least.
DHS is another park we hit twice. It is a small park but packed with Holiday Decorations if you choose that time of year. We go for RD once and then go for a later time to enjoy the nighttime entertainment.
We do build in time to just kick back and relax, we are not a commando family. If you do tis you will need at least a week, IMO.
I also think you may want to reconsider making a few ADR's. You cannot just walk into a restaurant in WDW, so if you have any specific restaurants you want to visit, I would make the ADR. If you want to be spontaneous and are not meal crazy ( my family is) then don't worry about booking meals until the day before or even a few hours before. But you need to book them. The way DIsney is set up, you really cannot walk up to a TS restaurant and be seated. You really will have to make the ADR.
One more tip I give folks who either have not been or have not been in many years. Subscribe to Touring Plans and fool around on the planner. WDW parks are deceptive in size, and that makes it tough to have a realistic view of timing. If you make mock touring plans you willl not only be able to have a general idea of how long it takes to get from one spot to another, you will be able to become familiar with the park layout. After over 14 years of multiple trips I still cannot find my way in or out of these parks! LOL! I think that even if you never use the plans, you will be able to create an outline to follow once you arrive in the parks, and that alone is a timesaver.
WDW is huge, and offers so much to do. You cannot do and see it all, so no matter when you choose to visit, you will need to manage your expectations. Have your family involve themselves in their top 3 things to do or see in each park. I always figure if we hit our 3 FP, and we respect the choices each person finds important we have done what we set out to do The rest is a bonus.
