So much depends on your relationships with them already, and on what you hope for in the future.
In an ideal world, I wish my brothers, especially my younger brother, saw more of my DD. She is changing so fast and she doesn't really know either of them - she's seen my brother maybe 5-10 times in her life and she's nearly 3.
I hugely wish my mother were nearer. It didn't seem so bad until a year ago, when she broke her leg badly. It made both of us realise that, realistically, things are going to get harder for her, health-wise, and she is going to get less and less able to come up to see us. I wish she were able to pop over for a few hours.
You might think you'll do longer visits less often and it'll be fine, but it's such a different thing. If my mum comes up for, say, a long weekend, DD is shy/overexcited for a lot of that time. Usually she's just settled down by the time my mum has to leave! You can't get the closeness you get from seeing someone every few days or every couple of weeks. And of course I can't easily ask mum to take DD for a few hours if I have an unexpected problem (though it's the relationship I care about more).
OTOH, I have a fraught relationship with my dad and with my in-laws, and I must admit that DP and I both agree we would not want either set of in-laws living near enough they could easily pop round all the time, because it has the potential to be awful! So in that sense, the distance has its positives.
