Hot sports are usually in the summer...so maybe it's just the wrong time of year.
All kidding aside though, if you're looking for a hotspot activated from another device, just refresh your WiFi network list until it pops up. If you're asking about the hotspot feature on the iPad, you must understand that this feature was not introduced until the iPad 3 (or later model), so if you have an older iPad, you won't have that feature. It should also be clarified that you would only see this option if your iPad is a WiFi + Cellular model (WiFi only would not show this function).
