Throwing this in the equation :
1 Diamond and 1 Gold from the 4 adults staying. Rooms to book are Suite, and 2 standard rooms (King or Twin dosen't matter). What would be the best combo in doing this ?
What I'm thinking :
Suite + 1 standard to be booked by Diamond. Ideally I would be able to claim since Suite already has Lounge access, the Diamond benefits should be applied to the standard room.
2 standard rooms to be booked by Diamond. Chance of a Suite upgrade, however if there is no Suite upgrade, seems I will have more to loose from this option as only 1 room will be entitled to Diamond benefit.
