I have friends coming from South America looking for decent low priced places to stay

I have a friend who’s bringing his young daughter to the states for the first time. They’re going to say in ft.lauderdale/miami. Im looking for recommendations on SAFE places to stay at a low price. Any suggestions for good hotels? Maybe airbnb or trustworthy motels

Edit: I’m thinking his budget is 100 or less a night.

I know that’s gonna be when it’s season so if anyone knows any good websites or apps that show low prices or maybe even a room sharing type
