Port Orleans Riverside or Coronado for a solo adult trip in July? Also need July advice

Ok, I know July heat is awful But I have an annual pass that I have barely used and I have time off of work in July. I am an adult traveling solo, my plan is to head to the pool in the morning and go to the parks after 4:30, to avoid some of the heat. Is that an awful idea? Do you think that would be bearable? I have stayed at Coronado and loved it, Port Orleans and Coronado are the same price which one to pick? I would like to just enjoy the hotel during the day. I would also be eating at the hotel often.
