Yes. Even configuring the 72 APs individually will be a nightmare, let alone monitoring and maintaining them.
Look at the ZD1200 (up to 75 APs) or ZD3000 (up to 500 APs) or the SZ-100 (up to 1000 APs). For 72 APs the total cost would be similar between these three units so it really depends how scalable you want it to be.
