(1) Lookup 'over the air' TV for your vacation house's zip code. Maybe be you can get the channels you want the old fashioned way with an antennae vs. a sat dish. Is the beach in a populated area or are you all alone in the woods ?
(2) I could live w/o TV forever, but no internet??? If you have internet then you can rebroadcast TV from your home to your vacation home over the internet. Many boxes sold do this. Or you can watch TV over the internet if the channel selection is OK for you. If no internet, then forget this.
(3) Many devices let you record your favorite shows to hard drive, then later replay them. This won't let you see the most recent episode or live sports, but if all you want is young kids TV or some droning noise in the background this works great, and you can skip past commercials. Record at home, then use a laptop with s-video out to connect to the TV, or use a TV with an HDMI connection.
