Getting around Fort Lauderdale

I’ll be staying beachfront in Fort Lauderdale shortly and I’m trying to understand the best way to get around to various parts of the area without renting a car. Hotel has bikes which seems kinda fun but I think it’s going to be blazing hot out which might seem less fun for the long haul;) Mainly want to get to some shopping areas and check out the city. Is uber my best bet? Read about something called LauderGo which seems interesting but don’t really understand what it’s all about. Any advice would be great! 😊
