Local multiplayer should be similar to the Wii, but better thanks to the Upad.
I think you and your girlfriend could have a great time with Nintendo Land and New Super Mario Bros. U, and Sonic & SEGA All Star Racing should do the trick while you wait for Mario Kart U. Rayman Legends will have a co-op mode so that may be another game to consider once it's released.
If you have the money then it would probably be worth getting one, and if you don't like it there's always eBay.
