DAY TRIP FROM AULANI TO BIG ISLAND

[dreamscometrue]

ALOHA!!
Looking for information for a day trip to the Big Island to see the volcanoes, etc.
As with all tours there are many to choose from, so I am hoping someone can share their experience to help me narrow the choices.

Also I have been looking into car rental prices and COSTCO seems to have the best prices - is that what others have found as well??

MAHALO IN ADVANCE

We had thought about doing this as well but was just going to book our own flight and car. Haven't ruled it out as of yet. Costco is who we rented with last summer.
