Welcome.
We use the bunk event thought there is just the two of us.
Because of back and other health issues for the wife, so she get
the jack sofa.
To get into the bunk I searched Amazon and found a wood bunk-bed ladder,
it came with nice metal hooks. I just stained it and clear coated it.
Made it easy to get in and out of the bunk. I was not expensive either.
The double recliners seem to me to be very "do-able".
Add 2 TV trays that could be stored away and you are all set.
Most dinettes are difficult to get in/out of anyway.
It sounds like a good plan to me.
