I am planning a trip to the big Island in June with kids ages six and eight. I would like to hear recommendations on Marriott waikaloa va Mauna Kea. I am using Marriott points. I have enough points to cover the Marriott waikaloa but would have to pay for an upgrade for oceanfront at Mauna Kea. I am not too concerned about the pools as we are spending a week at Aulani prior to our arrival. Any recommendations are appreciated.
