Some background: We are the great grandparents. We want to take our twin great grandsons to Disney World before we can't do it. My husband just turned 81 and we went for it this year and with scooters it was an okay trip with an additional friend along, no kids. It was an adult only trip this past December. I'm a seasoned veteran of Disney World; so, I'm not concerned about the ins and outs of the trip. I was able to schedule FP+ and optimize each morning in the park perfectly in our December trip. We did early entry every chance we could do it. We saw all the biggies across 6 days. We were even able to get a fourth fastpass on certain days and did stand by during the early morning entry hour. I doubt I will be able to get our great grandchildren or their parents to get up early enough to do the same results. We'll be lucky to get to the parks by 10 am. Anyway, we are only going to do this once in our life. Our great grandkids will be 5 years old next December. We want to do a trip right after Thanksgiving whatever year we do it. I think we will do 6 days in the parks concentrating on Magic Kingdom and Animal Kingdom with 2 days each in those parks and 1 day each in Hollywood Studios and Epcot. I'm not at all concerned about going when we can see all the new attractions coming, either. When would you go? 2018? 2019? 2020? or 2021?
