2 weeks to spend in the US

I will be this august in the us for 2 weeks and I’m not sure how to spend it I’m starting in Vegas with my family but then I have a week and half on my own that I want to go somewhere and have fun by myself

Just for context I’m 20 and I have around 10k to spend as my limit

I thought of going to Florida but from posts I saw August is not the best month to be there

would love to hear if you have any suggestions :)
