If you use the longer tubing, you can just put the pump under your pillow when you sleep. There will be plenty of tubing so you won’t get tangled in it or otherwise have issues with moving in your sleep.
I use the shorter tubing and clip it to my boxers at night. You can disconnect the pump for an hour but when I do that I still take a correction bolus, unless I did something strenuous during the disconnect period.
One more thing about a pump that I haven’t seen mentioned in this thread is their more modern features, such as the bolus wizard. You can set target blood sugars for certain times of the day, tell the pump what your carb to insulin ratio is, and then when you eat or have high blood sugar all you need to do is tell it what your blood glucose is, how many carbs are in the meal (if eating) and it does the rest. Some tweaking is needed on your part sometimes, but it takes a lot of the guesswork out of the equation. With a good doctor or other diabetes practitioner familiar with the pump, you can really nail this one down well.
My pump also connects to a CGMS, which reads my blood (actually interstitial fluid) glucose every 5 seconds, and sends an average every 5 minutes to my pump. The pump can tell you what your levels are, although not quite as accurately as doing a blood test on your meter. More importantly, it can accurately tell you if your blood sugar is moving up or down and how quickly it is doing so.
Good luck and feel free to hit me up if you have any other questions.
