"I was thinking that we should get a table, so that everyone has their own side, rather than a booth where I would have to sit on one side or the other. Opinions?"
Although in a booth you could sit in the middle, I suppose a table has more options for more kinds of configurations.
As long as everyone is eager to move forward with these get-togethers, there doesn't seem to be a problem with doing them. Just communicate a lot and make sure you know what everyone wants.
