I've been in California for over 5 years. During this time, my mother has come to visit me twice (both times after I begged her to come), one brother has come twice and his wife has come twice (separately from bro: I really love my sister-in-law). Over this time period, I've made it back home at least once a year, which on a grad student budget is pretty expensive and now I've got a lot of demanding experiments, which makes it harder to get away.
Last summer that brother and sis-in-law have moved out to California, to larger city 500 miles from me. Now that he's here, our sister made plans to fly out this summer with her kids, have me meet everybody in SoCal, do the amusement park circuit and road trip up to where I live. Sounds like fun to me!
Then my other brother and his girlfriend announced their own visit this spring. They're flying into SoCal, visiting big bro and want me to come meet them and road trip up to NorCal where I live. I can't make it all the way down, but I can probably meet them part way and host them a few days.
Now my mom and her two friends have made plans to come out to California this summer. Surprisingly, those plans include flying into SoCal and I'm supposed to meet them down there then we all road trip up to my end of the state. They're shocked that I'm not jumping for joy at the opportunity to spend a few days with them on a girls' trip.
After 5 years, suddenly everybody wants to visit and nobody seems to care that my vacation budget and time is extremely limited.
