Did you ask her or you are just sure without? I was adamant about 2 doors too at first too. But when I asked, wife insisted that she would be content with 1 door. For a couple of years I thought that she only said that to be nice. But things seemed okay with trial runs in rentals. Eventually I realized that she was sincere and that boarding procedure, although unpleasant, is only a minor problem in the overall scheme of things. The smell of gasoline, the waiting for rentals, the imperative to foresee when someone on board is going to want to pee -- all those things that make the door insignificant.
Of course having 2 doors is better, which is why Mooney is finally adding the left door. But you aren't in the position to be picky, or you would be looking at buying a Pilatus.
