Is this really a serious question?
I meen holidays? Really? Wtf would that have to do with you swallowing a pill or taking an injection if it happend to fall on an injection day?
No you cannot just stop a cycle, take a 2 week vacation trip , and then pick up where you left off. Your should plan your cycle out well in advance.
Can't really foresee family/dealth issues so if something happens mid cycle and you have to leave town for a few days/weeks your best option is to take your gear with you and continue as normal the best you can. If taking your gear is not an option and you will be gone for a significant amount of time then stop the cycle and begin your pct and take it with you instead.
