We recommend T's! Our stay, 8 adults and 1 child, was fantastic.
T was very accommodating with all requests.
As other reviews have mentioned, Waikiki Beach is a mere 20-minute walk. After the first day, we decided to drive and park at the Zoo's parking lot which is only $1.50 per hour and a much closer walk with all the gear we were bringing: cooler, chairs, floats, towels, etc. Use the pull cart we left behind!
Our favorite spot at T's was the back porch. Started and ended virtually every day there. We pulled up the chairs from the side yard table and had a blast.
If we go back to Oʻahu, we will definitely stay at T's again!
