We will be in Kona May 1st from 8-10 on RCI. There are no good excursions through the ship so we want to diy. 
We want to explore for about 8 hours so we get back to the ship in plenty of time. 
1. Is it possible to rent a car on Kona? Where?  Approximately how much would it cost?  Is it easy to get around on our own?

2. Can we hire a tour guide anywhere or is there a tour company recommended that might go to the places we want to go to?

3. Would 8 hours be enough time to go to volcanoes NP, black or green sand beach, and snorkeling at Kealakekua Bay?  If not what would be your must do’s?  These are the things different members of our family want to do (2 adults, kids ages 15 and 11). 
 

thank you!

Can someone confirm Omar’s email address? After emailing him to reserve I have not heard back to see if it is confirmed. Thanks.

Are there any beaches in St Thomas that have inflatables and other water toys/activities for kids? We are stopping there in September on Carnival Magic and are thinking we want that to be our beach day but want plenty of activities for the kids (ages 10, 7) to do. Also if there are what’s the best way to get there and the cost? Thanks.

Has anyone been to monkey jungle since it reopened? How was it? Our cruise in September stops in Amber Cove and we are thinking of doing this as an excursion. Should we do it through the ship (Carnival Magic) or is there an independent tour company you would recommend? How long is the ride there from the port? Thanks.
