Update. Finally made it to Oahu and we are learning now that all the major hotels were telling guests the same thing. It appears for transportation it might not be the hotels at fault after all.
@Marriott@Maui@CountyofMaui LIERS! Told us buses would take us to the Airport-NO, told us there would be planes waiting to take us to Oahu-NO. After waiting 8 hrs we have flights because WE found them, getting to Oahu only to not have hotel rooms! Thanks for nothing!
