Always thought about it because I do enjoy wine with dinner (especially on vaca). . .but figured since I can't always depend on hubby to help out (and in no way could I do it solo) maybe it wasn't worth it. BUT this time having my lovely SIL accompanying us, it would be completely do-able. So that a being said, has anyone ever tried it, or done the math? Is it convenient, economically sensible, or totally not worth it?
