Culebra day trip

Hi! So I just booked tickets to visit the island for the day 1230-930. The 530 tickets were sold out. Is staying until 930 a bad idea? I know the sun will set around 7/8, will there be things for a group of 4 to do! We're an adventurous group and plan on renting a golf cart!

One person in the group is worried there won't be much to do after 5/6pm.

Also any ideas/hidden gems to check out while we're there for the day?

We plan on bringing a cooler with snacks and drinks, but will there be other food options in case we get hungrier?

Are there paddle board rental options on flamenco beach?

Cheers!
