Hahahahahahaha, update on that: I complained to my mom about this, since if my dad keeps putting it off it'll be closer to February when he finally comes out (due to gigs and stuff). Now my dad is potentially driving out Saturday morning, coming Sunday to help unload/stay the night, and then leave Monday morning when I go to work. Which seems like a really short stay for a very long trip (he's driving), but maybe he just wants to see how long the trip is? I'm going to be facetiming my mom sometime this week to help her pack/identify what she should make my dad bring.
Main thing I'm concerned about is that my lease specifically states something about overnight guests/leaving guests unattended (since this is in someone's home, not a normal apartment complex), so I'll need to figure that out with them once I figure out if my dad is serious about coming out or not.
