I would try to do whatever you can to survive if you ask me. We say that usually kids need one day to adjust an hour of time difference if you push them by couple of time zones. It means that we your LO will adapt you will have to go back to Hawaii. And the process will start again:). So I wouldn't worry, let some sleep in or whatever - just survive:). And when you are home - try to jump into your old routine as quickly as possible: wake LO on the morning, cap the nap when it's 3pm etc.
