I chatted with Marriott through text today and they were able to talk to the hotel directly. However all they got from the hotel was just confirmation that the St Regis will be closed in June and July and the hotel did not say anything else. They told me to call the hotel directly myself when the reservation desk opens.
"I spoke to the hotel directly, they are not giving me any information on the closing for people with reservations, you will need to speak to the in-house reservations team. She did tell me that they will be closed during that time but would not give me anything else"
