1) Where to start in planning what parks to visit on which days?
I always start by looking at park hours, and EMH, which you either want to use, or avoid. That helps me to narrow down which days I want to go to which parks. If Fantasmic, OR Main Street Electrical Parade are only showing on certain days when you are going, then those might be a primary consideration as well.
2) Whether or not to buy hopper or "premium" tickets?
We have never use hoppers, never felt the need in 7 trips. My rule of thumb here would be, do NOT buy them. If and when you are in a park and feel like you really want to hop to another park, that is the time to upgrade your ticket.
3) Character meal? Daughter's 12th birthday on a Friday. Would YOU recommend breakfast or dinner?
We generally do character meals for breakfast before park opening so that they don't cut into park time. Our two favorites are Crystal Palace at MK, and Chef Mickeys at the contemporary.
4) We are not foodies and want to spend the least $ possible on meals. We are driving so can leave Disney property for meals if we choose.
Eating on property isn't about the quality of the food for me, it is the idea that it would likely take 2 to 3 hours to leave property for food. Do that for both lunch and supper, and you've lost an awful lot of park time out of your day.
5) Do all 4 parks require a full day or 2?
Depending on what rides / attractions / shows you really want to experience, Animal Kingdom could be half a day, as could DHS. We find that MK and EPCOT really are multiple day parks, and we usually manage to do one full day at Animal Kingdom and DHS.
6) I know it will be hot, but the conference dictates our visit.
Heat . . . . get free water at the quick service restaurants. Stay hydrated. Do shows, long rides, shopping, and long meals during the hot part of the day for a break from the heat. Rest when your body tells you to.
7) I am not a detailed planner - would rather make spur of the moment decisions, but that doesn't seem like a wise decision for WDW.
No, I don't think it is. Lines get quite long, restaurants (at least table service ones) fill up. If you don't have some plans going into the trip, or lots of experience in DW to work off of, I think that might not work out well.
We are a family of 4 - kids are 2 girls ages 10 & 11 (will turn 12 while we are at WW). They are past the "princess" stage so we are not planning a lot of meet and greets. We went to DL in 2012 and spent 4 full and 1 partial park days. We weren't ready to leave. We spent a lot of time tracking down characters.
Having been to DL many times, it is confusing translating it into 4 parks. Having to schedule meals and FP months in advance is making my head spin.
Thanks for any advise or telling me where to look!![/QUOTE]
