It's is hot late June/early July, but for summer that's when we like to go. We get there around 6/24 and leave around the 4th. We did stay for the 4th last year, but didn't do anything special, but they do show fireworks the 3rd and 4th. (The 3rd is the prep. fireworks) We were at BCV and they were really loud...much more than normal. This year we are leaving ON the 4th. We do the parks before the 4th. I hate heat. I hate to sweat, but I've gotten used to it. I sweat more than the regular person as it is. I just put on eyeliner, a sunvisor, and sunscreen. A dip in the pool always cools you down too. You'll have a great time.
