I'm one of the Admins for the Friends of Belair Beach Facebook group, and as such I try to stay in touch with Belair Hotel management. Last night I received an email from interim GM Jennifer McCrae with the following, published with her permission:
I am pleased to let you know that the air conditioning on the other side of the hotel is working and cooling the rooms as expected. Our housekeeping staff is busy getting the units ready for this weekend as we are looking forward to "welcome home" so many of our timeshare owners and new guests. As for the hot water, we have been experiencing some challenges that we are still trying to work through and this has caused the hot water to be turned off for long periods of time. However, please be assured that our team is diligently working on it.
Jennifer

This has been a long haul, as in six months or more. Here's hoping the problems have finally been resolved.
