@Maria16515 It feels to me as though you are trying to fit far too many guests into your house. 4 bedrooms = 8 guests for me. Also, whilst hard to tell from the photos, you don't seem to have dining and seating capacity for 8 let alone 12. Finally can you really turn the house around in 4 hours or do you plan to block a day between guests? It may be your market demands 11am out and 3pm in but we have managed very successfully with 10am and 4pm.
