There are Cruise ships in the catalog that have nothing below the main deck so I have been trying to assemble my own solution to this. Generally there is no allowance for guest rooms below deck, no stairway, elevator or ramp. This accessway with hatch flush to the deck and door to the guest quarters below links exterior with interior. There are nodes to ascend or descend on the stairs and aligned well the link to both areas is complete. See my catalog for the Cruise Guestrooms; You can use the links above to redecorate or continue shopping. No refunds, exchanges or special requests for custom pieces please. Use this well and watch your kilobytes...Enjoy
