Presidential vacations are ridiculously over sensationalized. Opponents of any sitting president crucify the president whenever they take a vacation as there's always some crisis. Republicans did it with Obama, Democrats did it with Bush, etc. The reality is that the President never really takes a vacation. The President can do his job from anywhere. It's all just rhetoric.
Honestly, when there's something like a hurricane, you don't want to president calling the shots. You want career bureaucrats who have decades of experience in emergency management calling the shots. The president just needs to sign the emergency declaration and step out of the way.
