The very stripped-down timeline that has worked for me a number of times is thus:
1. Reserve a campsite at Whitney Portal for the first night. Get there mid day, and relax while you acclimate. Get a burger. Camp the night.
2. Get up not particularly early and hike to Trail Camp, and get there sometime in the afternoon. (Remember to move your car.)
3. Get up at some dark hour (3 or 4 am) to hike to the summit. Leave everything at Trail Camp except a small pack of water and essentials.
4. Come down from the summit and retrieve everything at Trail Camp. Curse at marmots. Depart.
5. Repeat next year.
