I used to tour commando style, and park hop, and go to the parks on arrival day, and on departure day if my flight left late enough (which it usually didn't.) I'm now a 2x cancer survivor and I simply just cannot do that anymore. I do go during the slower times, usually October, though this year, we will be going down in November, but also a slower time. I do not live close to an airport and I need to take two flights to get to WDW. We get up super early and I never get any sleep the night before. So, when I get to the resort, it is just unpack, and eat at the resort and call it an early night and hopefully get some good rest to start the trip off rested. Since I spend two days out of my trip traveling, I make my trip for 8 nights, this way, I have 7 days in the parks. I do 3 days in MK, but 1 is either a
MNSSHP or
MVMCP, I have two days for Epcot (one day is from rope drop to close, and the other is just a partial day), 1 day for AK, and 1 day for HS. If you need to take a break during the day, and you know that will go well for you, do it. Get to the parks at rope drop and go back when it starts to get crowded and then break at the resort and go back in the afternoon with scheduled Fastpasses. For me, with the shorter park hours when I go, I do not go back to the resort to take a break. I find it more tiring. I'm not a pool person, and I don't take naps, I wake up feeling worse and with a headache. If I leave the park, I lose my momentum. So, I make sure that I do at least one nice long table service meal a day, and I enjoy seeing all the shows, getting off your feet and in the AC is restful. I may have nodded off in Hall of Pres and maybe Ellen....

I try and tour the parks with minimal walking. Example, try and do Fantasyland and Tomorrowland on one day, and Frontierland , Adventureland, and Liberty Square on the 2 day. Give yourself permission not to feel like you need to do everything. If you're tired, or not feeling well, pack it in for the day, and rest up for the next. Trying to stick it out when you are feeling awful ruins that time, plus possibly the next day too, if you need the rest. Last year, much to my dismay, I had to leave AK early. I didn't want to, because I really wanted to be there at night, but it was the right call, and I was able to get rest and start the next day feeling better. I don't park hop, and I don't travel to other resorts or parks to eat my meals, I just stay at that park and eat there. The one exception, is I have started to eat at a resort prior to going to our hard ticket party. This year, we have an ADR for afternoon tea at the Grand Floridian before we go to MVMCP at 4pm. That morning, I just will wake up whenever and relax at the resort, since it will be a late night.
I found once I gave myself permission to go slower and not feel badly or guilty about it, because always being an a type personality that was hard, it went better and was more relaxing for me. It has worked out pretty well for me the past two years, and I'm hoping I will do well this year, too. I do push myself a bit much, but I no longer work, so when I get home, I can catch up on sleep and rest up.
I hope you have a wonderful time.
