Has anyone managed to to cash upgrade from beach bungalow (points redemption) to sunrise overwater villa recently (e.g. last couple weeks)? I contacted the hotel requesting a cash upgrade and the hotel tells me that the sunrise overwater villas are fully booked. However, marriott.com is showing 3+ sunrise overwater villa available, and hotels.com allows me to book 5 sunrise overwater villa for my stay period. I wonder if the hotel is purposely holding back sunrise overwater villas for revenue as oppose to them eligible for upgrade.
