Thinking of booking 1A/1K for my partner and myself LAS > MAN for next year. Will be my first time in any business class. Definitely will want to get some sleep, and we do not need to talk to each other. Any reason I should consider switching to 1D/1G in the middle for the two of us instead? Would prefer to have the option of a window. Its the leisure config so only 16 seats in UC. Any reason to preference one side of the plane vs the other? I know there is only a bathroom on the K side so not sure if there is more traffic over there.
