I'd agree, plan a route that gives you a short cut home if you need it, and then you probably won't. On the other hand, if the weather turns against you, or the wind is very much in your face, don't be discouraged if you do have to short cut.
Definitely have a lunch stop. Either a nice cafe, or take a packed lunch (but it might be chilly this time of year, and a cafe will have tea). Don't have anything too heavy, and give it time to settle. Soup is good.
Raisins are a good snack to carry too, if you like them. In fact I didn't used to like them much, until I started taking them along as a handy sugar boost.
I think it's great that you're doing this together - company makes rides so much easier. You'll soon pile on the miles.
