First time cruising with NCL. This may be a stupid question, but I have to ask. We recently booked and the package allows for two nights of specialty dining. If we book a specialty restaurant that does not have fixed prices, like Teppanyaki, we would use one of our specialty allowances and pay any upcharge on the menu correct? It that's the case, we'd not want to use our last allowance at a fixed price specialty restaurant, but save it for another specialty restaurant that's ala carte right? Pay out of pocket for Teppanyaki?
