So this is a weird one...
The Ritz-Carlton official site still says coming soon and has a single concept art on the main page - this hasn't change in at least 1 year.
I found this video on YouTube which is just a bunch of photos and concept art (I think a lot of them are from this site to be honest) and it lists this website - www/sienna-tamudabay.com. Sienna were the investment firm behind the Tamuda Bay project with Ritz-Carlton as the operator. It made me wonder if they were still working on it and, to my surprise, the website no longer exists and the URL is actually up for sale.
I can't find anything later than 2017 that mentions Sienna being involved but there is also no real reason to believe they have pulled out of the project as we know work was still ongoing since then.
Anyone have any ideas on what's going on there?
