July 2022 update
After a couple years' cancellation due to COVID, the Hawaiian Festival ("4 Days of Aloha") returned to Esther Short Park in 2021, which I missed. In 2022 it was held the weekend of July 21-24. The first 2 days were classes & workshops, Thurs night was a party, Fri night was a concert. Saturday festivities were performers & dancers all day, as well as vendors. Sunday was a 5K/10K run, and a multi-cultural program representing the many peoples of Hawaii. All events/days had a ticket price. I had determined to go on Saturday. In previous years the Saturday festivities were free, but it costed me $10 to get in. I got my ticket ahead online, but plenty of people were buying them at the gate.
On my way into downtown at 6th St, I saw a handicapped sign with an arrow. Considering the amount of traffic and the probable difficulty of finding parking, I followed the sign. Not only did I encounter handicapped parking, it was in a garage (costed me $4 for the day), so that my car was protected from becoming an oven.
I've been in a wheelchair for 30+ years. It poses some challenges for traveling. Maybe others can benefit from my experiences.
