Old-timer,
I would just get an early start to enjoy the morning, and the firmer snow conditions. No need to camp unless it's something you really want to do. Don't know about you, but after spending ten years in the infantry I like sleeping in a bed as often, and as much as possible.
The hike itself is pretty unique as far as hikes go. In July you'll have plenty of daylight, and plenty of people around you.
Take as long as you need or want. Just carry plenty of water and sunscreen. Enjoy the views, and go on a bluebird day if you can.
Man I miss home.
