Ours was similar. It was a group lesson where we all mimicked the leaders steps, then we broke up into twos to practice holding hands at arms length. There was no dancing "cheek to cheek." After our lesson, we watched the people who had come to the milonga to dance which was much more interesting than doing the lesson. If you sit toward the back of the room, you can watch to your hearts content; but if you sit up front, you will probably be asked to dance by a local. The milonga itself is worth exploring, its a 1920's building with two floors. The dancing was on the second floor. We were there just a few hours and the atmosphere was so nice, we wish we could have stayed longer!
