1997 2520 Bench seat questions for family of 4

[Island Dreamer]

My wife and I have two kids ages 6 and 11. The Parker I have being delivered next week will have one passenger seat on the port side. I have the option of having one kid and one adult inside while underway and having the other two on the deck with bean bags. If I were to take out the single seat, are there dif models or years for a good bench seat that I would want to replace it with?
I would ideally like my wife and two young kids be able to be inside while underway. Also, I noticed that on the videos that Greylight Fishing posts, one of the kids sleep on the bench seat with the other in the isle.
