Can someone help with product recs for the Vegas heat?

I am heading out to Vegas soon and I need help with product recs for my limp 3a, fine, pourous hair. It doesnt hold curl very well also it gets weighed down very easily and last time I was there my hair looked like a limp, frizzy mess the whole time. Any help would be greatly appreciated! TIA
3a fine, normal porosity, low elasticity
