We are two experienced divers but this is our first time diving Kona. So glad to leave our drysuits behind!!! We hope to dive 5 days and plan on one night dive (mantas). Would appreciate any input. Are there any small boats with shade run by reputable operators? Who are your favorable operators overall, and who do you recommend for the manta dive? Prefer boats to shore diving, will be staying in Kohala but will have rental. We arrive next Friday, will be there a week plus. Many thanks!
