I've never needed more than 25' of coax to connect to park cable but we carry plenty more for our portable sat dish. As mentioned above, park cable is normally low quality, standard definition video with limited generic stations to choose from.
Unless we are staying for a quick overnight stop, I always take the 5 minutes to set up our sat dish on a portable stand delivering all the same channels we have at home. Been doing it for years and the routine is quite simple once you get the hang of it.
