I have a couple session in mirage and goes to fs.

If you get the room with hard mattress. Not good for massage as your little bro squashed like you laying on the floor. But for fs good

If you get the room with those air mattress, massage feels good but not for fs, as you cannot hold your ground firmly as you pumping lol

I think the best one should be air mattress and hard mattress in 1 room hahha
