I have done the couples 50 minute massage on the Wonder. They bring you and your SO into a room with two tables. There was two message therapist. They worked on us both at the same time and at the end they put my hand in my husbands hand where I proceeded to laugh really hard. Sorry, it was just really corny.
Anyways, I really enjoyed it and it felt no different then having a message by myself.
Edit to add: they did push product at the end, but I just simply said thanks but not at this time. I didn't feel the stress to buy. Was it annoying, sure, but just kindly say no.
