Sorry, I can't answer your question and although I have some ideas, I would not want to speculate.
Instead, I have one in return: what is your reason for stopping the pump?
If it is a concern about air travel, I don't believe there is a problem - I fly a lot with my pump.
If it because you will be swimming a lot and in situations where you cannot wear your pump, I understand. Although, I tend to reconnect every hour and give myself a boost of my hourly basal dose before jumping back into the water.
Personally, I would be worried about adding another unknown to my diabetes management when on holiday in addition to more exercise, different food, different stress and, maybe a little more alcohol. So have always stuck with the pump.
