Can I run a Phantom without a fixed line internet connection?

[redalear]

Hi! I'm planning on taking the phantoms (2 + dialog) out to the lake house for the weekend. There is no internet nor cell service. Can I still operate them? I am hoping that with an Apple Airport Express I can create an internal wifi network that isn't actually connected to the internet, manually connect the dialog, which will wirelessly connect to both phantoms... and just play from Spotify Connect with my offline catalogue? Or my computer with a external hard drive of music?

Any help would be appreciated. Thanks!

Sure can.
