We got confirmation about 3-4 days before our trip. However our flight got delayed and we ended up missing our transfer to Bora Bora. I messaged the hotel that morning through the app 3 hours before our new arrival time but I guess Hilton doesn’t check their messages often. When we got to Bora Bora, there was no one from Hilton. A rep from IHG was able to call the hotel for us but it took them an hour and another call 30 minutes later for someone to finally get us.
