Car Needed for Family Vacation

Planning a weeklong vacation with two young kids and staying at a hotel (Hilton WPB) next to city place. The hotel has a shuttle availability and was wondering if a rental car would be needed.

Looks like the shuttle does airport transfers and can also take you locally to places like the beach for free.

With activities/pool at the hotel, and being able to walk to city place, do you think we’ll be okay without a rental car?

Thanks!
