St. Regis Mauritius Resort, Le Morne, Mauritius [Master Thread]
No worries TR.
The St Regis wins on room design, overall layout of resort, setting, beach and water activities, and has a slight edge on service quality (butler service).
The Westin is cheaper, has better F&B, a club lounge with a nice cocktail hour (not much food but great cocktails), and better location on the island if you want to visit other places.
Of course it's all subjective, and we're comparing at a high quality level (meaning there are no really bad things here). Feel free to PM for specifics, I hope I'll get around to writing a review for the Westin.
One thing I will say, I booked a half board rate for the LUX Belle Mare on the internet, as a normal customer without any loyalty mindset. This was fantastic value at a great hotel, given the food inclusions. So there are options beyond SPG.
