For the guest room you could add a portal to a new "map" where you could chose to make as many rooms you want to quick visitations.
or
Use a portal for private decoraded rooms suited for the NPC :)

Having a door to another map is the easiest solution, that's true. Generally, I try to keep the size of the various floors coherent (the inside are also roughly twice as large as the outside, to vaguely keep things in scale), which is why I'd like to avoid this if I can. Then again, so far we don't really get guests, so maybe I can just use the guest room and pretend nothing is wrong.
Ahh I see yeah that would be a shame to mess up something you have ben so meticuless in keeping :hmm:
perhaps a basement Rooms then .... well even cells depending on the girls and boys who visit her's kink is ;)
haha True you could just keep the using the guest room liek that :Dyou know how it is there is always someone who will notice and point it out ;)
