I agree - go by yourselves.
We took our daughter to Maui for Thanksgiving when she was 2. We flew ORD-SFO-OGG. Although everything went well, when she woke up at 2:00 AM the first morning, my wife and I realized for the first time there was a 5 hour time change for her to get used to. It took several days and many trips from Wailea to Lahaina so she'd sleep in the car.
We had a nice time, but don't plan on bringing her or our son back to Hawaii until they're old enough to appreciate it.
