I was wondering if Pokemon Ranch needs a constant internet connection to work?

The only internet connector I have for my Wii has to be wired to my computer, and the Wii is on the other side of my bedroom. To connect it to internet, I have to string the cable across my room. Which is no problem if I'm downloading something, but I can't leave it that way for very long

So, to use Ranch, do you have to have an internet connection hooked up while you're using it? I don't want to spend the Wii points to get something I can't use without boobytrapping my room.
