The trick to it, as I saw right here on Tug, is to do the sunrise the morning after you arrive on Maui. Your internal clock will still be on Mainland Time, so you'll be ready to get up early. Make the drive up the mountain, enjoy the heck out of the sunrise, and then head back down for the balance of your vacation. The rest of the nights you're there you won't have to worry about it, and it's something you can check off the bucket list. We did that on our last trip, and it worked like a charm.
Of course, there is also something to be said for taking off the wristwatch and turning off the alarm clock, and just relaxing your way through things. Hawaiian time...
