Tuttle Creek and Alabama Hills are great spots. Days will definitely be hot, nights may cool off. I stayed at Tuttle in summer several times and was comfortable at night-it can be windy. YMMV. Bishop itself is also hot, but has access to many areas at 7000 ft. or above where it is cooler.
If you're in Lone Pine area and forecast is for hot with possible hot nights, you can always stay at decent Boulder Creek RV park with full hookups.
Good recommendations. Since your first day will be a long one you'll probably get to Lone Pine toward evening so it will be cooler.
