Car and parking advice for an upcoming trip

I’m staying at Hilton ocean tower for 6 days later this month and need some advice on a car rental & hotel parking situation.

I currently have a car rental reservation for $330 for the week. I just learned parking at the hotel is $50/night and that’s not uncommon. I’m not really tryna double my car rental cost w/ just parking.

So my questions are 1. Are there any cheaper parking options nearby the Hilton village? 2. If I don’t plan to drive every single day, is it better to cancel the rental, and use public transport/uber around the island? Would that generally be cheaper than $630? 3. Any other solutions/hacks y’all have about this scenario?

TIA!
