I agree on all your points. Sounds like you have a similar role to me.
Myself and a colleague went on a training course in Leeds for a week expecting a trainer at the front of the room. Turned out we were watching him teaching another group in London on a big screen in our room. Worst of both worlds!
I can better that. A little under ten years ago I had a meeting in Nottingham, with a 09:30 start. This involved walking over two miles from my home to Shipley, then a train to Leeds, change for Sheffield, change for Nottingham, then a three mile taxi ride to the site. On arrival there was just one other attendee & the presenter, who then just sent us a PP to go through which took about 20 minutes.
After a lot of cursing and the 20 minutes, I caught a bus back into Nottingham then wandered around for a bit until the pubs opened for a few on works time beers before heading home!
I work in the IT Industry and very rarely go into the office these days. My local office is 1/2 hour away but the team office is 2 1/2 hours away. I can go months without seeing a colleague - daily conference calls with WebEx are employed to keep us in communication. When I do go to the team office, I get a lot of "while you're here..." taps on the shoulder so don't actually get a lot of work done. I also work a lot in Data Centres on my own which can be a very lonely job sometimes.
At a push I can go from door to home office desk in around 55 minutes, although more realistically it takes about 1h10-1h20 depending on the connections. Until recently I was in every day, but working in an area with a lot of video & standard conference rooms, as well as flex-desks it can get very noisy as visitors roll in & out. Not ideal when I'm coding, and need absolute concentration. So I'm slowly ramping up my home working to 2-3 days a week, and eventually I may head in for a day every other week. We don't really have a team office, face to face meetings are arranged at different sites around the country to give everyone at least one or two short travels.
And as I said earlier its proving to be very productive for me, I'm already approaching a ten hour day here at Bantamzen HQ, and got a heck of a lot done! So those get banked for maybe an early finish tomorrow. Although on the down side my better half has cottoned on to the fact that I'm better positioned now to do a lot of the household chores when she's at work. But on the flip side again, I am only a few metres away from the wine rack & whiskey cabinet if I'm having a very bad day. Oh well, the rough with the smooth I guess (but not the wine or whiskey)...
