At this time, only 2 person sex is available. There are plans to make 3-somes, etc... in the future; but for now the only way is with a little imagination.

Well actually only 2 people can engage in sex in each bed,  so for all practical purposes only 2 people can have sex in the rooms at a time. The "3 person" and more rooms aren't locked to the 2 person-per room limit, so this is where the imagination factor kicks in. If invited in the room, the other person(s) can either watch the activities or they can use imagination and join in.
