The Le Meridien Tahiti deflagged in 2018. I had a redemption there, booked earlier in 2018, for 2 nights in February 2019 prior to a cruise; ultimately I cancelled and stayed at a beautiful Air BnB.

Le Meridien Tahiti

On October 16 of this year [2018] Le Meridien Tahiti became a Sofitel. They alerted people with reservations with just 4 days before the change was effective. I suppose this helps with people rushing to redeem points or book cash reservations before the changeover. It seems to be a common theme for Marriott to not provide customers fair notice. Guests who have already booked to stay at the property will have their reservations honored. Customers holding reservations should have received an email similar to this:

“As a valued Marriott Rewards member, we are writing to inform you of a change in the status of Le Meridien Tahiti. Since October 16, 2018, the property is no longer part of Marriott International or Le Meridien brand and no longer participate in the Starwood Preferred Guest (SPG) program. We see you are currently holding a reservation, arriving on xxx 2019 and departing on xxx 2019. We are pleased to inform you that the hotel will honor your reservation for a Preferred (free) Night Award, including Cash and Points, as your stay was originally confirmed. However, since the hotel will no longer be affiliated with the Starwood system, you will not earn Starpoints for any eligible charges incurred, nor will you receive any of your Starwood Preferred Guest membership amenities or benefits. We realize this may be disappointing but hope we can count on your understanding.”
