@Cii0 I see that you have 3 listings: for one room, two rooms and whole house. This is fine; you will just need to block the dates on the other two calendars the minute you get a booking. Most hosts on this forum suggest you turn off Instant Booking if you are juggling calendars.
I was a little surprised at your pricing poligy: the 1 Private Room is only £50 (for two people), while the 2 Private Rooms are four times as much per person at £419 (for 4), especially if, as you say, you block the second room when someone books one room, so that they don't have to share a bathroom. You also let the whole house for £460. I'm sorry about the currency being in £, but you get the idea.
However, I'm sure you know your market better than I do, especially when the Golf Open is on!
