HI Bloodworks, my boyfriend and I are actually doing an event to hike Humphrey's July 30th and i was just given the opportunity to snag july 29th off work also so might turn it into a double summit bagging trip if interested!
As for nice hikes, Cabin Loop is nice and there is some water, check the trip description for more info. I always suggest going north during the summer for the not-so-crazies, but for myself and my man...if we had 4-6 to explore and hike...we would most likely end up deep in the heart of the Superstition Wilderness, not for the faint of heart, too hot for normal folk.
Good luck picking a hike or two! There are some nice backpacking adventures to be had along the Arizona Trail as well Imight add!
