You don't have anyone to check on the tank while you are out? If you have a trusted reefer nearby, might want to get their info and ask if they can help.
Might want to install a camera to keep any eye out on your tank. I'm considering getting one when I have to travel in the summer. Definitely, empty your skimmer/skimmate locker. Refill everything (ATO, cal/alk, etc.).
Have fun in Hawaii and Bali! And congrats on the wedding.
