Not to be a pesamist but don't count on it on long trips.

I don't mind even wifi with a small fee. I'm addicted to my computer. On my trip I stayed 12 nights in 11 campgrounds not including the ITG.. All were private and were considered better campgrounds. 2 had no wifi. 2 had wifi but it was so weak it was unusable. 1 had wifi but it was down. 1 had a wifi access in the office only whch was colsed when i got there. The remainig ones were great. Of course if you are planning a shorter trip, you can be more specific. Its difficult and inconvenient to find other places like MacDonalds or Starbucks that also have wifi while traveling. Even if they say they have wifi, don't count on it. By the way, the wifi at the ITG was excellent!
