Currently Banyan Tree Bangkok CMO.
I have a stay in a couple of weeks and I recently got an email, that, due to a refurbishment:
please be advised that our iconic Vertigo Rooftop Restaurant, Moon Bar, and Saffron Restaurant will be temporarily closed for refurbishment from 15 June to 28 November 2026. During this period, alternative dining experiences will be available within the hotel, and our team would be delighted to recommend suitable options during your stay.
Nothing on the website when I booked about this and in my booking it is still welcoming me to partake of those very same facilities.

When I pointed this out to them, they said alternative facilities will be available and offered me a 30% discount on them.
