Concur with MB, alot depends on the family, and of course that Brett will be along shortly.
You see all sorts of arrangements during training, geo bachelors, SNAs/SNFOs with thier significant others flying in every weekend, whatever works, I guess.... Big flick for me, this training is your one shot, don't get attrited because you were distracted. That distraction could be worrying about family/significant other that isn't there with you, or they could be there and constantly complaining about your studying and not giving them attention, etc...
I have seen it first hand, and I am sure many of the IPs on here currently instructing can see some of those stressors also. Just don't put yourself and your family in a position where its them vs. training. That training should be priority #1 for you.
