I personally believe some sort of bonding period is great for remote people. I've worked in a kind of "worst of both worlds" setup where I went to an office 8-5 but I worked with a completely remote team (the office was basically a place for me to put on a headset and ignore everyone else).

But we met on a planned company trip (with the excuse of a Vegas trade show, we went and met one week early) and that helped immensely with bonding and team building.

If I manage a remote team, I'll push for a similar team bonding exercise whenever possible.
