We're coming to the BI at the end of May and will be staying at the Marriott Waikoloa. Our flight leaves at 9:30pm. Does it make sense to try to check in somewhere else (albeit for 8 hours or so)versus trying to use the hotel changing room before we catch our flights? We're only going to be on the island for 6 nights and have so much we want to do. Just thought it would be difficult to live out of suitcases for the day.
