if you are going to be nontechnical, and if you are going to let your ego take the wheel by building a resort-wide wifi rollout, and if you are going to scab as much money as possible by charging silly money and using the cheapest possible gear, and if that cheapest possible gear means using a rinky dink little RB750 as the edge firewall and walled garden - if you are going to do all of that - then at least make sure you patch for CVE-2018-14847 yeah?
