Another vote for Charley’s - there are 4 of us with bags so Uber was going to be risky if we got a small car, and UberXL can be pricey. We could book a minivan through Charley’s that fitted us all nicely. Also used them from Aulani to Waikiki, I was keeping an eye on Uber for that trip too but pricing was all over the place, and pre booking XL was going to cost $30 more than the Charley’s flat rate.
