Speaker Placement Help

I need help deciding where to place my speakers at my lake house. I have 2 in wall speakers and 5 in ceiling. Out of the 5, 2 are regular speakers and 3 are angled surround speakers. The main purpose of the speakers will be for playing music while entertaining. The TV placement is not know yet, but i am not concerned about any surround system factors that may play into it. My main concern is where to place these 7 speakers to not only look good but sound good as well. I was thinking about placing the two in wall speakers on either side of the patio doors. But for the ceiling i have no idea where to place them, maybe 2 in both the living room and dining room and one in the kitchen but i have no idea. attached is the blueprint any assistance or tips would be greatly appreciated.
