I booked a couples massage for my husband and me during our wedding trip. It was at the GF, though, so I can't give you first-hand SS spa info. It was very nice. We were in a large room that is separated by an arch, so we could see each other.
A note of caution: you can request a female therapist, but like room requests, it is not a guarantee. I requested 2 female therapists and we had 2 men. I was fine, but my husband was a little weirded out to have a guy touching him (and to have another man touching his new bride

). But he would still do it again in a heartbeat.
The SSS couples package sounds very nice.
