To add a bit to this, and I thank you for your submissions... at one park we stayed, we were given a password to use to sign in with.
We had our MacBook open, and then we tried our tablet. Nope, that password was in use and it was necessary to sign out, and then sign in again with the other device.
That little trick definitely limited us, and likely many others. Is this effectively limiting usage? It certainly limited us!
At another very expensive golf park they said they were limited by the location. This was in Borrego Springs. They said it was impossible to get more bandwidth because of the remote spot. We doubted that.. but $$$$ for a site sure did not buy even a passable opportunity for wifi.
I do appreciate that there is other methods to access the internet for some, but I am Canadian, and we do not have the opportunity to have internet via cell phones like many posters.
