I don't have to be at the front of the pack, I usually just travel with 1 other person, so my normal morning, even when traveling with 3 other women, is get up, I take a bath at night and wash my hair before going out at night/before dinner/after mid day break and I always make sure my clothes are already pressed and hanging up, so I do sunscreen and throw on my clothes, run to grab coffees and a collection of fruit, a yogurt whatever, some pastries and then back to the room where the others are getting ready. I eat/drink espresso, do makeup and brush my teeth. Sometimes I'll make mimosas to go (because its vacation and I'm like that). Takes about 30 minutes total in the Swolphin, or YC. I just get stuff from the coffee cafe places. If I wake up late, I'll get an Uber or towncar to get to MK/AK sooner, I know the walk to Epcot or DHS is no more than 20 minutes, if that, so that makes the morning equation easier. 6:30 would be a TON of time for me, but that does not account for children. I think it also depends on if you need a hot breakfast to sit down at, and where you're staying, but regardless, 6:30 is a lot of time, you'll be fine!
