So, if a middle aged married couple were enjoying the same activities as he and his bike and were so engrossed they did not notice anyone enter their hotel room, and were observed by the cleaning staff pursuing the same activity and/or carried on regardless, does the same apply to them? Which one goes on the sex offenders register, him, her or both.

If you were shaggin in the shower (with the water running) you would not necessarily hear anyone knocking on the bedroom door. So would you then be guilty too. A bit difficult to cover yourself up under those circumstances.
