Cabo in June?? Which hotel should we pick?

We really want to visit Cabo in June for the first time. How the weather there that time of year? Also, I cant decide between a few resorts. Either the Riu Santa Fe Los Cabos, the Hola Grand Faro, or the Melia Cabo Real. We want a good all inclusive resort, with good food and good service. Also, what are the "must sees" in Cabo? Thanks in advance!
