HI I have two listings, one is for 2 rooms at $285 per room and the other is for 1 room at $285 per room. The two rooms is for 4 guests and one room is for 2 guests. I assume that if someone books for one room then any 2 room booking will be void so that they do not cross over. see listing references 46939277 and 14455593. Also I am not sure what additional area mean, one is showing 7 and the other 11. Your help would be appreciated.
