Wifi concerns

[BulldogsRus]

Hi guys, just bought a silver to use up at our lake home and after reading some posts here I'm getting a bit concerned. We plan on using this outdoors for the beach, and our router would be approx 50' away inside our home. Using Spotify I'm worried about dropouts or limited connectivity with this thing. I used to have a Bose box with an iPad connected, then would simply use my phone to connect to tether to the iPad via Spotify without issues playing music on the fly. Are these units so touchy via wi-fi that I'll have constant connectivity issues, or do I need to invest in a wifi extender? Or is it necessary to buy that Dialog (I only have one silver)? Because there seem to be alot of posts calling it a nightmare with dropouts and half hour resets, which would be embarrassing with a beach full of dancing people!

Talk me down off the ledge, any advice is greatly appreciated!!
