Wingo, why would you not want to practice touch and go's. I did loads once I got my solo and even more once I was hour building.
Circuit bashing is dammed useful the more you do the eaiser it gets, sure beats just flying from A to B and back again, you might as well do some T&G's especially as it does not cost anything at most US airports. Hell I did loads of night ones with and with out my landing light. There is no skill in just flying straight and level you should try to improve your landing technique every time you fly.
I have no idea why this school have stopped T&G's but I can only imagine it is for safety reasons.
