We are planning a 4 night stopover in Kona and will be staying at probably the Keauhou Beach Resort, the Royal Kona Resort, or the Courtyard (not decided yet). Instead of renting a car, We had planned to just get a taxi to/from the airport and take a couple of day tours from our hotel (one day for the volcano stuff and one day for the observatory). On our third day we will be happy to just hang out at our hotel.
Does that sound reasonable to do without renting a car, or are we really better off renting a car anyway? Since we are just there for a few days, we are looking to keep things simple and would rather just enjoy the scenery while someone else worries about the driving. (Not to mention that we would like to save the extra cost of the rental and parking.) But, I am hearing that almost everyone rents a car there and that taxis may be more expensive and less convenient than we'd hoped. (It's our first time to Hawaii and we're not sure what to expect.)
Any comments/advice would be appreciated!
