I really like the Carnation Cafe so I say yes! You don't have to make a Priority Seating, but you can. I like to just so I don't have to worry about waiting for a seat. Since Main Street opens earlier than the rest of the park I like to make an early PS and people watch Main Street as everyone waits for the rides to open. I'm usually finishing up my breakfast just after the rides open and then I can head right to them.
