Doesn't sound snobbish:) personally, my family can't afford it! However, lots of gymnastics gyms in my area don't want to work with cheerleaders who want to learn how to tumble and not learn stuff like vault and bars etc. I've tried classes but they are very slow moving and often only an hour long. I've also had a couple of privates but they cost like 30 british pounds at least (don't know what that is in dollars!) so they can't be a regular thing for me. Can't speak for anywhere else apart from the UK but as our cheer world develops, more and more squads are starting to offer tumble classes but it's hard when most teams (including mine!) don't have their own gym so training space is not always accesible :(
