We have been using slingbox for years with moderate success. As Danemayer said, it all depends on campground WiFi speed and how many are using the WiFi. Early mornings and late evenings are when we have the most success. The main problem is people camping out on the WiFi even though not actively using it. Often we request the campground to reset the WiFi adapter which will force those actively using it to reconnect. Those who are not are removed. Often times connecting to the slingbox through the Web Player is more successful as compared using the desktop application, that I am not sure why, but it does work. Also, if you have unlimited data which reduces speed when you exceed your plan limits on your phone you can engage the phones Mobile Hot Spot. Even the limited speeds available after you exceed your data allocation is still many times faster than campground WiFi. Hope this helps.
