Flight
Round trip tickets are about $700 this time of year (we did this on purpose to make it as affordable as possible in hopes you can make it) Most people are staying October 31st- November 7th. I would recommend coming 2 days prior in case flights get delayed.
House Or Rental
We got an Airbnb in Lahaina for our stay. There are plenty of places on Airbnb or Vrbo for your stay that are reasonably priced! Our wedding planner informed us to stay on the west side of Maui because there is only one road that can get us to Olowalu Plantation House (our venue) from the south side of Maui and sometimes that road closes.
