Do you actually get the free Atlantis stay with matched status?
Yes I did it and got the free stay.
I did it a few months ago when TR was matching Mlife gold to TR Diamond basic level, matched both myself and my wife.
Called Atlantis and booked 2 rooms in the Royal tower. When I got the confirmation email the fine print said they may charge me if I dont gamble enough so did HUCA a few times and all reps pretty much said it's not enforced so I went and only used the $100 free slot play from each room, I won $$$ and didn't play anything else (had my kids with me).
Resort fee was about $55-$60 per night.
Got connecting rooms which were pretty nice, and we had a great time! Also used the free shallow water dolphin interactions - 1 per room.
