Roll20 and Google+ make a good combination for remote gaming. I play in a regular Wednesday night AD&D campaign, we his Session 63 last night. This was the second time I had to be on the road for work, and use the hotel wi-fi to get online so I could play.
Different towns, different hotel chains, different wi-fi experience. It works, it lets you get by, but it is a challenge sometimes. I could spend a lot of money for anywhere access via a national phone company, but it would be a waste of money most of the time.
The things technology allows us to do and the ease it can bring to finding a gaming group is wonderful, but the inconsistency of internet access when on the road makes it a challenge.
At least I have the option to do it, even if I had to juggle my schedule so that I am in a motel so I can play, instead of travelling on game night. It’s not that big a stretch, I’m not driving until 2 or 3 in the morning to get home. It’s not worth it. I tried sleeping and driving once, I don’t recommend it. I’m also trying to get completely over being sick, not relapse.
