So my fiancé' has never been to Disney...we are both 39. We do not have kids. We would like to go to Disney and do a few parks. He wanted to go in July but I suggest it is very hot then. I have been a lot but mainly in early Spring. When would be a good time between basically June to Sept? Rates more or less the same all those months? We plan to stay in a rental offsite from Disney. We would like to do Disney, Universal, Seaworld and maybe Discovery Cove.
